Custom PVD Coatings

BryCoat can tailor a coating for your specific application. Custom designs are used in cases where the performance of a standard PVD coating does not meet design requirements and the value of the application or the quantity of parts supports a customized solution.

Many of these custom coatings involve multilayer designs to address specific problems such as erosion resistance.

A note about new improved coatings:

  • TiCrN
  • TiAlCN
  • TiZrN
  • CrAlN
  • CrAlCN
  • AlCrN
  • Multilayer designs
  • Nanolayered coatings
  • Nanocomposite coatings
  • Diamond like coatings

There are myriad coating choices available today. Many of these new improved coatings tout special properties and improved performance. But, before you specify one of these coatings for your application, consider the big picture.

Titanium Nitride has only been around for about 20 years in precision component coating applications. This is a very short time compared to nickel and chrome plating applications. And, still, the hard chrome plating market is much larger than the TiN market.

In the last 15 years, we have repeatedly seen the launch of the next great product that will replace TiN in the market. But, TiN is still the most widely used PVD coating. Many of these replacement technologies are touted for higher hardness levels. But, there are more factors that influence performance than just hardness. Some of these technologies are great for certain niche applications, but do not provide good performance across a range of applications. And other technologies can be created in the lab, but do not scale well to economical production.

Titanium Nitride is still the most commonly used PVD Coating. It offers a versatile combination of high hardness along with toughness, inertness and adhesion to a wide range of substrate materials. It is low in friction and has good release properties. Because it is so inert, it reduces tribochemical reactions that lead to degradation of fluids and counter-parts. It also prevents microwelding with counter-face materials that leads to galling, fretting and seizing of moving parts.

CrN is excellent in applications requiring higher temperature capability than TiN. TiCN is excellent for increased resistance to abrasive wear.
