Objectives:

Evaluate UltraCem® Coating

Proof of Concept for Pistols/PDW’s

Endurance Testing

Environmental Testing


Process Development Stage

• Levels of Process Application

• Level 1: Basic Coating Parameters• For individual part feasibility demonstration

• Strip original coating

• Establish pre-treat and coating process based on metallurgy specified in drawing package

• Apply coating thickness based on best approximation or historic data

• Level 2: Early Prototype Coating Parameters

• Level 3: Advanced Prototype Coating Parameters

• Level 4: Production


Chemically deposited Nickel-Boride coating

Columnar growth Coating

Uniform thickness regardless of shape or metal alloy

Coefficient of Friction UltraCem™: .08

Hard Chrome: 1.3 - 1.35

Gunpowder residue doesn’t stick to weapon parts

Residue and coating does not bond chemically

UCT Defense’s UltraCem™


Claimed Benefits Superior mechanical wear resistance

Metallurgical bond to substrate

Superior hardness

Ductility – no brittleness

Low coefficient of friction

Uniform coating thickness

Corrosion resistance

Highly temperature resistant

Environmentally friendly process (Chrome Replacement)



Weapon Preparation:

Pistols stripped of OEM finish and chrome barrel lining

Nickel-Boride deposited on parts

Uniform thickness around parts

Parts were coated by UCT with little input from ARDEC

Quick dimensional analysis

Tested fired by UCT before shipment

Weapon functioning was verified


Three M9 Pistols and One UltraCem™ 92FS

Firing Sequence

M9 - 120rnds then cool (Eight mags), 130 rnds then clean (Eight 15rnd mags, One 10 rnd mag)

UltraCem® - 120 rnds then cool (4x) then clean

Non-destructive testing (NDT) inspections at 5k, 10k, 14k, 17k, 20k, 22k, 24k, 26k, 28k, and 30k rnds

Targeting and Accuracy every 5k rnds

Endurance Testing:


Environmental Testing:

Three M9 Pistols and One UltraCem 92FS 500 rnds fired at 60° C (140° F) and -40° C (-40° F)

NDT inspections before & after

Endurance Weapon:


Total cost ~ $12K = large amount of good information

No noticeable mechanical wear

No apparent gun degradation after 15,000 rnds

Easy to remove some residue

Hard to Clean Carbon

A thin layer of CLP on the gun could aid in carbon removal

**Not a Chrome Replacement in Barrels**
