Wear Behavior of Plasma - Sprayed Alumina - Titania Coatings |
| Abstract |
Wear resistances of plasma-spray coated alumina, alumina-titania of 3, 15 and 40 wt.%, and pure titania were tested by measuring the wear rates of samples, which were pressed against the rotating cast iron plate with an oil-alumina abrasive. Wear rates of the coatings were compared between samples to determine the optimum composition of the powder in the slurry wear application. Wear rates of the coatings made from the composite powders were nearly the same, with the alumina-15 wt.% titania coating showing the lowest rate of wear. It is shown that alumina-titania composite ceramic can yield coatings wish superior microstructure and wear resistance. |
