OVERLAY

T168i

T168i is a revolutionary new material specifically designed to provide extreme wear and impact resistance. Having the ability to be heat-treatable, meaning it preserves excellent performance before and after standard quench and temper heat treatments.

T168i provides the best performance in aggressive environments where impact and abrasive wear are critical sources of material failure.

In terms of wear resistance, the high density of complex borides and carbides in a martensitic matrix allow it to compete with the wear performance of WC/Ni overlays at a substantially lower price point.

The extremely fine lamellar structure of the complex borides and the spherical morphology of the carbides allow for impact performance 20X that of WC/Ni, and chromium carbide overlays (CCO).

Applications

T168i overlays are suggested for use in any applications where abrasion and impact resistance is required. The revolutionary improvement in impact resistance and toughness will typically result in an extended lifetime over WC PTA and Chromium Carbide coatings.

Impact Resistance

Low energy high frequency rotary impact test at 8J requires a result of less than 3 grams material loss after 24 minutes is considered a pass. After 24 minutes the T168i had 0g loss.
