Adhesive strength and structure of micro-arc oxidation ceramic coatings grown in-situ on LY12 aluminum alloy WU Zhen-dong(吴振东)1, 2, JIANG Zhao-hua(姜兆华) 1, YAO Zhong-ping(姚忠平)1 1. Department... and morphology of the coatings were studied by XRD and SEM. The adhesive strength of ceramic coatings was assessed by thermal shock test and tensile test. The results show that the coating is composed of m-ZrO2......

Effect of reinforcement content on the adhesive wear behavior of Cu10Sn5Ni/Si3N4 composites produced by stir castingK.Sanesh,S.Shiam Sunder,N.Radhika摘 要:adhesive wear, whereas that at high loads was severe delamination wear. An oxide layer was formed at low velocities, whereas a combination of shear and plastic deformation occurred......
displays a few adhesive trace and abrasive grooves, and there are a few fine flake-like wear debris presented on the wear scar (Fig.6(a)). In the following 4 000 cycles, the wear scar further increases... and sub-surface layers[8]. This stage is also associated with adhesion between the magnesium alloys in fretting contact (see Fig.6(a)), which results in that the adhesive wear becomes the predominant......
of adhesive wear. Second, the plastic deformation work would increase due to the increase of normal load, so that the surface damage is more serious, resulting in accelerating the wear. Figure 7 Effect... of abrasive wear and adhesive wear, respectively. Figure 9 SEM images and corresponding EDS spectra of worn tracks for peak-aged Cu-15Ni-8Sn alloy under different friction conditions: In severe wear regime......
wear mechanism of rare-earth/MoSi2 composite is adhesive wear. Key words:MoSi2; wear mechanism; dry friction; rare earths; [全文内容正在添加中] ...Dry Friction and Wear Characteristics of Rare-Earth/MoSi2 Composite 龙春光1,张厚安1,陈平1,刘心宇3 (1.Institute of Material Surface Engineering, Xiangtan Polytechnic University, Xiangtan 411201, China;2.School......
. There is evidence of adhesion and ploughing on the Al worn surface, which shows a distinct characteristic of abrasive and adhesive wear. The counterpart pin is seized twice in the wear tests, which may... scars in the worn surface of composite become smaller and more, and the evidence of ploughing become shallower, comparing Figs.4(a) and (b). It is suggested that the abrasive and adhesive wear......
, and the plastic deformation exists in certain area. So it can be judged that the wear type of the upper specimen is spalling wear and adhesive wear. In addition, Fig.1(d) shows the typical surface morphology..., and the mechanism of wear is spalling wear and adhesive wear. The wear of wedge sets is less serious and appears to be slight spalling wear. 2) After analyzing the internal structure, working......
