Lightweight TiC/Ti alloy wear resistant coatings for lightweight materials in aerospace applications
- Drexel Univ., Philadelphia, PA (United States)
Plasma spray deposition of titanium and up to 80 vol% titanium carbide (TiC)/titanium matrix composite materials have been investigated for their applicability as wear resistant coatings for protecting light weight substrate materials, such as aluminum. Studies of the air and low pressure plasma sprayed TiC/Ti coatings were completed and are reported. The coatings were characterized and the influence of processing methods on structure and the subsequent wear behavior of the coatings is reported. The investigation includes the effects of spraying in air, controlled atmosphere and in shrouded spray systems. Coating hardness values are reported and wear rates and friction behavior on aluminum substrates in ASTM C99-93 Pin-on-Disk (P.O.D.) wear testing are characterized.
