[13] also pointed out that the self lubricating effect of cu element improved the wear resistance of hea at high temperature, which was higher than the wear resistance at room. Abstract. this work presents the performance of the copper (cu) based functionally graded coatings (fgcs) when subjected to corrosion in the 3.5 wt% nacl aqueous solution and sliding wear under the different loads (2, 5, 8 and 10 n). the cu fgc, with three layers of cu (each 20 μm thick), has a gradual decrement in the crystallite size from.

In this study, cu al2o3 graphite solid lubricating coatings were deposited on the 304 stainless steel substrate by low pressure cold spray technique. the influences of cu coated graphite content on the microstructure, mechanical properties and dry sliding wear behavior of the cu based solid lubricating coatings were investigated. the results showed that the mixture addition of al2o3 and cu. The wear tests results revealed that elemental cu positively affects the wear resistance properties of the ti–cu alloys. nanoindentation testing results showed that the moduli of the ti–cu alloys were minimally changed at increasing cu content, whereas their hardness evidently increased according to the wear test results. The effects of the squeeze casting process on the microstructure, mechanical properties and wear characteristics of hypereutectic al–si–cu–mg alloys have been investigated by optical, scanning and transmission electron microscopy and mechanical property test; the wear behaviour was investigated using a pin on disc configuration; alloy ingots were prepared by gravity casting, liquid.

Enhanced electrical conductivity and mechanical. Reactive powder composites cu (0–15%)tih2 containing up to 5% native cu2o were manufactured by high energy ball milling and then hot pressed to produce bulk nanostructured copper–matrix alloys reinforced by cu3ti3o inclusions. two high energy ball milling (hebm) protocols were employed for the fabrication of cu ti alloys: single stage and two stage ball milling, resulting in an order of.
