Surface Treatments & Coatings

 Surface treatments and coatings allow us to improve tooling performance when the characteristics of the tool's substrate (base material) have reached the limits of capability. Surface treatments like Oxide and Nitride were among the early arrivals. They addressed the need for added lubrication and surface hardness to improve part finish, reduce or tolerate heat generated by higher machining speeds, and wear-resistance.

 As materials evolved, so did the available treatments to either improve tool performance, or compensate for the challenges those new materials presented to Manufacturing.  Hard coatings like Titanium Nitride (TiN) offered improvements in wear-resistance for HSS tooling. Titanium Carbon-Nitride (TiCN) arrived to compensate for the limitations of TiN, especially in respect to Titanium Alloys. Titanium Aluminum Nitride (TiAlN) followed with improved tolerance to heat generated by increasing machining speeds and material resistance to the tool. Each new coating is developed to succeed where another was not well-suited to the application.
