“…Quinn et al classified the interface temperatures into a real contact temperature and a nominal contact temperature, and achieved the corresponding computation formulas. [13,14] So, they simplified these mathematical analyses and achieved a brief approach to the calculation of the interface temperature. [15,16] Although these computation formulas can estimate the variation of the interface temperature to some extent, the accurate value cannot be achieved due to the complexity of real contact surfaces.…”

The dry sliding wear tests of H13 steel were performed under atmospheric conditions under various ambient temperatures and loads; the wear performances and the wear mechanisms were studied. At room temperature (RT), the wear loss of the steel gradually increased with increasing the load. An adhesive wear prevailed with little tribo-oxides on the worn surfaces. Under the atmospheric conditions at 473 K (200°C) and a load of 100 N or above, a mild oxidation wear prevailed with about 20-lm thickness of tribo-oxide layer forming on the asperities of worn surfaces. The wear loss first reduced and then slightly increased with increasing the load. Compared with the other ambient temperatures, the wear at 473 K (200°C) retained the lowest wear loss due to the protection of the tribo-oxide layer. As the ambient temperature reached 673 K (400°C), the wear loss increased with increasing load, leading to higher wear than those observed at RT and at 473 K (200°C). The predominant wear mechanism at 673 K (400°C) was oxidation wear, unlike mild oxidation wear, which dominated at 473 K (200°C).

“…Since the first observation of oxidational wear by Fink [1], there has been much development of the theory. Most notably, Quinn and co-workers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] have published a comprehensive theory for oxidational wear that is now the widely accepted basis for interpretation of worn surface morphology in the mild wear regime. The theory is reported to be broadly in agreement with experimental observations of oxidational wear (e.g.…”

A detailed transmission electron microscopy study of oxide and oxygencontaining phase formation during the sliding wear of metals, composites and coatings is provided. A wide range of different materials types are reported in order to compare and contrast their oxidational wear behaviour: a low carbon stainless steel, a H21 tool steel containing 7% TiC particles, a 17% Cr white iron, an Al-Si / 30%SiC composite, an Al-alloy (6092)-15% Ni3Al composite and finally a 3rd generation TiAlN/CrN 'superhard' multilayer coating. For the ferrous alloys, nanoscale oxides and oxygen-containing phases were formed that exhibited excellent adhesion to the substrate. In all cases, an increase in oxide coverage of the surface was associated with a decrease in Lancaster wear coefficient. The oxide at the surface of the 316L and H21+7%TiC was found to deform with the substrate, forming a mechanically mixed layer that enhanced surface wear resistance. Evidence of oxidational wear is presented for the wear of the A-Si-30%SiCcomposite, but this did not give a beneficial effect in wear, a result of the brittle nature of the oxide that resulted in detachment of fine (150nm) thick fragments. The worn surface of the Al-alloy (6092)-15%Ni3Al and TiAlN/CrN coating was characterized by reaction with the counterface and subsequent oxidation, the product of which enhanced wear resistance. The observations are related to the classical theory of oxidational wear.

“…Under pressure and in an environment of relative motion, solutions that polish through abrasion rub the wafer surface. The contact point may produce an instantaneous high temperature, causing the alumina and oxide layer to adhere together and undergo a solid-state reaction [20][21][22]. The adhesion junction is sheared and slides under the action of friction, and the oxide layer is cut down and carried away by the flow of the slurry, successfully polishing the silicon carbide surface.…”

Silicon carbide, a third-generation semiconductor material, is widely used in the creation of high-power devices. In this article, we systematically study the influence of three crucial parameters on the polishing rate of a silicon carbide surface using orthogonal experiments. By optimizing the parameters of chemical mechanical polishing (CMP) through experiments, we determined that the material removal rate (MRR) is 1.2 μm/h and the surface roughness (Ra) is 0.093 nm. Analysis of the relevant polishing mechanism revealed that manganese dioxide formed during the polishing process. Finally, due to the electrostatic effect of the two, MnO2 adsorbed on the Al2O3, which explains the polishing mechanism of Al2O3 in the slurry.
