Ti—6Al—4V合金微动磨损的表面防护

Surface Protection Technique Against Fretting-Wear of Ti-6Al-4V Titanium Alloys

分析对比了Ｔｉ－６Ａｌ－４Ｖ合金经喷丸后抛光、火焰喷涂Ｃｕ涂层、等离子喷涂锡青铜、Ｃｕ－Ｎｉ－Ｉｎ和ＷＣ／Ｃｏ—Ｉ涂层、爆炸喷涂ＷＣ／Ｃｏ－Ⅱ、Ｎｉ－６０和化学镀镍磷镀层等处理后，在室温和５００℃下的抗微动磨损性能。结果表明：ＷＣ／Ｃｏ－Ⅰ涂层有较好的综合防护效果．

Abstract: Shotting-peen, fire-sprayed Cu coatings, plasma-sprayed Sn-bronze, Cu-Ni-In and WC / Co-I coatings, explode-sprayed WC / Co-Ⅱ and Ni-60 coatings and chemical planting Ni-P are investigated and compared for the performances of several surface protective treatments againet fretting-wear of Ti-6Al-4V titanium alloys in room-temperature and 500℃.It shows that plasma-sprayed WC / Co-I has good integrative protective performance.
