摘要:

AbstractA promising use of metallic alloys such as stainless steels, Cr-Co-Mo alloys, and titanium alloys coated with ceramics such as alumina or hydroxyapatite is in biomaterial applications. This procedure can lead to a good combination of properties: corrosion and wear resistance and beneficial bioreactivity from the coating, together with the necessary high yield strength and toughness of the metallic substrates. Results of wear tests on AISI 316L stainless steel, with and without alumina coatings, are presented. The adhesion of the coatings has also been evaluated.

摘要:

AbstractA cast Al-10.6 Si alloy has been laser surface alloyed with 9.4, 15, 19, and 35% Si, the coatings have been characterised, and the dry sliding wear against a cast iron surface has been investigated. Except for a few pores, the coatings were relatively uniform in composition, microstructure, and thickness, and had high integrity and continuity with the substrate. The microstructure was very fine, the eutectic composition being displaced to approximately 17% Si. The wear rates of the base alloy, the laser surface melted base alloy, and the laser surface alloyed coatings were similar. The microstructures of the worn pins and the worn cast iron rings are described and discussed. The mechanism of wear is by adhesion, extensive plastic flow, and fracture.
