PVD Coating Services

Overview
Nitron™ C is a robust coating that delivers excellent release and wear properties, improving corrosion resistance with a low coefficient of friction. It reduces abrasive and fretting wear on tools, decreasing downtime and extending tool life. Non-reactive, non-absorbent, and non-additive, it meets FDA standards and REACH regulations, making it a superior alternative to hard chrome plating.

Applications

• Moulding
• Anti-Stick
• Punching
• Forming
• Abrasion Resistance

Mechanical Properties

• Silver/Grey Finish
• Coating Thickness 1-4µm
• Hardness 1800-2200VPN

Capabilities
Wallwork Cambridge has six Nitron™ C based machines, each with a 200KG limit.

Overview
Nitron™ CA provides exceptional oxidation resistance and hot hardness, making it perfect for demanding cutting and forming tools. It maintains its hardness at temperatures up to 1050°C, allowing for application before heat treatment without loss of integrity. These qualities make it an excellent alternative to traditional barrier coatings. Nitron™ CA can also replace thermal diffusion processes such as HVOF and is fully compliant with FDA and REACH standards.

Overview
Nitron™ DX is a duplex coating system designed for enhanced wear resistance and load-bearing capacity in demanding applications. It integrates a hardened layer diffused into the base material, which can then be coated with Nitron™ C, CA, CX, or Ti. The process uses relatively low temperatures, minimizing distortion or material growth. Nitron™ DX is fully compliant with both FDA and REACH regulations.

Applications

• Forming Tools
• Mould/Casting Tools
• Dies
• Slitting/Cutting Tools

Mechanical Properties

• Black Finish
• Diffusion Depth 10-50µm
• Diffusion Hardness – Up to1200VPN
• Coating Hardness – 2800HV
