Fatigue behavior of plain specimens of low carbon steel subjected to small tensile prestrain is investigated through rotating bending tests and the mechanism of the decrease of fatigue limit due to the prestrain is discussed. It is found that 3 percent prestraining causes the acceleration of both slip and crack initiations, and increases the growth rate of a small surface crack of less than 0.3 mm. It also decreases the fatigue limit. If prestrained material is aged, the fatigue limit increases. These effects of the small prestrain are explained based on the unpinning of locked dislocations due to the prestrain.

Nanostructured and conventional titania (TiO2) coatings were thermally sprayed using air plasma spray (APS) and high velocity oxy-fuel (HVOF) processes. The fatigue and mechanical properties of these coatings were investigated. The fatigue strength of coatings deposited onto low-carbon steel showed that the nanostructured titania coated specimens exhibited significantly higher fatigue strength compared to the conventionally sprayed titania. SEM analysis of fracture surfaces revealed valuable information regarding the influence of these coatings on the performance of the coated component. Analysis of surface deformation around Vickers indentations was carried out. This investigation gives new understanding to the nature of fatigue and deformation of these coatings.

In order to determine an effective coating film for cutting carbon steels with a coated cemented carbide tool, tool wear was experimentally investigated. Low carbon steel (AISI 5120H steel) was turned with four kinds of physical vapor deposition (PVD) coated cemented carbide tools. The coating films used were TiN coating film and three kinds of titanium-tungsten-silicon-aluminum based coating films, namely (Ti,W,Si,Al)N, (Ti,W,Si,Al)C and (Ti,W,Si,Al)(C,N) coating film. (Ti,W,Si,Al)N, (Ti,W,Si,Al)C or (Ti,W,Si,Al)(C,N) is a new type of coating film. The following results were obtained: (1) The critical load of three kinds of titanium-tungsten-silicon-aluminum based coating films was higher than that of TiN coating film. (2) The hardness of three kinds of titanium-tungsten-silicon-aluminum based coating films was higher than that of TiN coating film. (3) In cutting low carbon steel, the wear progress of three kinds of titanium-tungsten-silicon-aluminum based coating film tools was slower than that of the TiN coated tool. (4) In the three kinds of titanium-tungsten-silicon-aluminum based coating films, the wear progress of the (Ti,W,Si,Al)N coated tool was the slowest.
