Hard Chrome

TiCN Coated Pressure Die

Hard chrome is the industry standard for coating mandrels, mandrels being used for bending most materials except stainless steel.  Providing good wear protection and lubricity. Having a low friction coefficient of .17 is approximately .0005” thick.  Its hardness being around 900 HV, it can withstand temperatures up to 1200°.

T.D. Process

Thermal diffusion is a slick carbide coating that is about 3200 – 3800 HV in hardness.  It is applied .0002 - .0003” thick and can hold up to 1100°.  T.D. has a friction coefficient of .2 - .3.

TiN

Titanium nitride is a vanadium carbide spray.  It has a friction coefficient of .4 and a thickness of 2 – 4 microns.  It’s a general purpose coating with micro hardness of 2700 HV and max working temperature of 1000°.

TiCN

Titanium carbonitride has a friction coefficient of .3 and a thickness of 2 – 4 microns. It has a higher micro hardness of 4000 HV but a lower max working temperature of 800°.

Carbide Spray

The best way to describe carbide spray is “spray on sand paper”.  Providing roughness to any grip area it’s applied.  Instead of eroding the material it adds dimension, so must be taken into consideration.  An added benefit is that the coating can be stripped and renewed.
