A Future “Design Classic”

- Bright Chromium

Alan Gardner

What is a “Design Classic”?

• “Design Classics” are icons in the world of fashion and trend. They are easy to recognise yet are so familiar they become part of every day living. They often go unnoticed. They always remain true to their original concepts

• They are more often noticed when they have unexpectedly changed

• There endurance is due to qualities that cannot be easily measured and they don’t become classics overnight

• We are aware of them even without knowing the influence they have on our lives

Evolution not Revolution …

• During their evolution, design classics tend to

retain the key features that make them

appealing…

– Note the Coca Cola logo remains consistent

Change Vs Evolution

• Iconic Endurance

– An iconic design can change, yet its intrinsic appeal can remain or

even grow

– We remain attracted to its values despite these changes

How far can Evolution go…

• Surprisingly…providing the original concept

and values are clearly reflected in the product,

company or service we embrace changes

Image or Name …

• Design Classics can be recognised equally

effectively by images, names or services:

• Coca Cola

• Mini

• Starbucks

– The iconic form is not critical, but its values are

Sustaining Values …

• How many here are truly Design Classics….

Why Bright Chromium is Iconic…

• Iconic Designs

– Recognised without need for description

– Universally appreciated & valued

– Sustains Core Values/Principals/Virtues

– Not Diluted by Evolution

– Multi Lingual

– Imitations always compared to original

– They endure through almost all changes

Bright Chromium…Appeal

• In France & Italy…almost 50% of the chromium

electroplate is consumed by Fashion and Cosmetics

Bright Chromium…Fashion

• A true Design Classic is always in demand

despite changes in fashion and trend…

Bright Chromium…Innovation

• A true Design Classic is always in demand

even at the leading edge of innovation…

Bright Chromium…Technology

• A true Design Classic always delivers…even

when designs and technologies change

Bright Chromium…Enduring Value

• A true Design Classic can continue to enhance

value through many design generations

Bright Chromium Technology

Bright Chromium Advances…

Trivalent Hexavalent Deposition Modes

Bright Chromium Advances…

• Latest generation trivalent chrome systems

deliver the same unique metallic style but with

added benefits:

– Choice of colours

– Meet Environmental, HSE and Productivity needs

– Experienced worldwide applicator base

– Tough metallic films with high performance

– Can’t be matched by paints

Bright Chromium…Options

• Colour evolutions open new markets and opportunities

Bright Satin Dark

• TriMac

– TriMac trivalent chrome systems offer

colours plus high performance from

environmentally sound chemistry

– TriMacIII conventional chrome colour with

excellent performance

– TriMac RM a warm colour with maximum

“Russian Mud” corrosion performance

Bright Trivalent Systems …

Darker Trivalent Systems…

• Twilite

– The first chrome to break from tradition,

Twilite has been adopted worldwide as a

new look stylish chrome

– Twilite a cool darker shade that brings a

subtle new look to metallic chrome, also

provides excellent performance in

“Russian mud”, CASS and NSS

Very Dark Trivalent Systems…

• Galaxy

– Galaxy is rapidly gaining a reputation

amongst designers as the new look dark

chrome

– Galaxy’s cool blue/gray shade works well

with modern fabrics and textures, it also

gives performance to match standard

chromium

Specified by General Motors (M24)

The Satin Revolution…

• M-Satin …

– Satin chrome has sparked new opportunities in design studios. Stylish options in satin chrome include systems with highly consistent gloss and colour

– From the very light to dense and heavy, satin continues to win over designers in all application areas

– It has now started to appear on external automotive parts

Bright Chromium and Performance…

• Trivalent Chromium is solving the problem of Russian Mud !!! A BIG issue in some countries during severe winters…

The Future…is Bright !!!

Chromium continues to be specified by major OEM’s:

• Automotive demand is at its highest for 20 years

• Technology is improving to meet higher standards

• Environmental pressures are driving technology

• New finishes are attracting designers

• Bright Chromium on plastics is preferred route

• These are hallmarks of a “Design Classic”

PVD Coatings for Hydrogen Economy Applications Introduction

• Motivation: Coatings for the Hydrogen Economy

• Miba Coating Group & Teer Coatings Limited

• The Magnetron Sputtering Process

• Industrial PVD Coating Technology

• Coatings for PEMFC Bipolar Plates

• Other potential applications:

Electrolysers: emissions reduction & fuel generation

• Towards Scale up

• Conclusions

“With a driving range and performance

comparable to ICEs, FCEVs are the lowest

carbon solution for medium/larger cars and

longer trips. These car segments account

for 50% of all cars and 75% of CO2

emissions, hence replacing one ICE with

one FCEV achieves a relatively high CO2

reduction.” McKinnsey & Co, Sept 2011

Motivation: the growing Importance of PEMFC for future FCEVs

Coatings for PEMFC Bipolar Plates Thin film Physical Vapour Deposited coatings are relevant

• PEMFC Bipolar Plates have multiple functions Electrical conductivity, flow field for gas distribution, water

clearance, structural stability, etc.

• Low interfacial contact resistance & high

corrosion resistance required

• Thin stainless steel foils (0.1mm or less) – save

weight & space (cf graphite) & economically

formed into channels, but relatively high ICR +

corrosion (= ICR↑ & risk of MEA poisoning)

• Coatings needed with low ICR & good stability

Noble metals, transition metal nitrides, carbon…

_diagram_pem.gif http://en.wikipedia.org/wiki/File:Pem.fuelcell2.gif

Coatings for PEMFC Bipolar Plates

• In state-of-the-art PEMFC, ICR between the

materials contribute 55% of the total I2R losses,

dominating the ohmic loss contributions C.J. Netwall, et al, Journal of Power Sources 227, (2013) 137–144

• 10nm Au coating has been suggested to improve

ICR of stainless steel BPPs S. Hirano et al, Fuel Cell Seminar & Exposition October 18-21, 2010

• 100’s BPPs/stack, so 300,000 FCEVs/year could

need ~14kg of Au, even for 10nm coatings!

• Reducing Au required: Treadstone Technologies

Hydrogen via Electrolysis - Transport

• H2 from “on board” alkaline electrolyser (ITM Power)

• Improve combustion + exhaust after treatment: Emissions

• Powered by “waste” energy (e.g. regenerative braking)

• H2 optimises cold start (exhaust catalyst activation temp )

• H2 periodic injection to purge Lean NOx Trap (LNT)

• H2 used in Balzac is

• H2 could also be generated

locally, from other renewable

sources (wind, solar, etc.)

• Future: H2 expected cost

PVD conditions can be selected to produce dense, corrosion resistant interfaces

combined with high surface area electrode coatings for efficient electrolysis.

PVD Coatings for Hydrogen Economy Applications Towards scale up: from batch processing to serial production of coated plates

Coating equipment for different volume scenarios:

Equipment suitable for prototypes and lower volumes

Equipment for volumes up to 300k parts: In-line device with higher efficiency

compared to conventional batch equipment

~10 € m-2 both sides coated, fully utilized machine, for say 300,000 m2/year

PVD Coatings for Hydrogen Economy Applications In line, load-locked, semi-continuous processing concept

• PVD coatings are essential to protect and improve the

performance of multiple components vital to the Hydrogen

Economy.

• Stainless steel BPPs, e.g. for PEMFC, need lower ICR and

improved corrosion resistance.

• Economic “duplex” nano-structured coatings, such as

Graphit-iC™ FC2, can significantly reduce the ICR of

stainless steel PEMFC BPPs, and reduce corrosion.

• High Surface Area (HSA) coatings can enhance the H2

production rate from electrolysers and substitute for

expensive PGM catalysts..

• Industrial PVD technology will support pre-production batch

processing and future serial manufacturing requirements.
