“…The increased microhardness and improved wear resistance were attributed to the combined effects of FSP-induced microscopic grain refinement and finer-scale microabrasion in the FSPed zone. Similar findings were reported by Eskandari et al [ 63 ] in FSP of AISI 430 ferritic stainless steel wherein mild adhesive wear with 17.4 times improvement in wear resistance. The formation of the dual-phase microstructure of ferrite and martensite with fine grains on the surface was found responsible for improved hardness and wear resistance in this type of steel.…”

Friction stir processing (FSP) technology has received reasonable attention in the past two decades to process a wide range of materials such as aluminum, magnesium, titanium, steel, and superalloys. Due to its thermomechanical processing nature, FSP is used to alter grain structure and enhance mechanical and corrosion behavior in a wide range of steels. The refinement in grains and phase transformations achieved in steel after FSP affects hardness, tensile properties, fracture toughness, fatigue crack propagation rate, wear resistance, and corrosion resistance. A number of review papers are available on friction stir welding (FSW) or FSP of nonferrous alloys. In this article, a comprehensive literature review on the FSP/FSW of different types of steels is summarized. Specifically, the influence of friction stir processing parameters such as advancing speed, rotational speed, tool material, etc., on steels’ performance is discussed along with assessment methodologies and recommendations.

“…This remarkable development is typical of SPS operation promoted by the high temperature of sintering and low heating rate during the experiment [26,38]. Moreover, increased wear rate can be facilitated by large plastic deformation of the ductile matrix, whereas incorporating a harder reinforcing phase (h-BN) in the ductile matrix to some degree can lessen its ductility thereby reducing the propensity to wear easily [46,49]. The mechanism for improving the wear resistance properties of the composite can also be attributed to the inherent lubricating effect of the h-BN reinforcing phase on the worn surface, which in turn resulted in enhanced load bearing capacity of the surface and improved lubrication as wear proceeded [50][51].…”

The effects of different combinations of spark plasma sintering parameters: temperature, pressure, heating rate and holding time, at three levels on the microstructure, densification, mechanical and wear properties of Ti6Al4V/h-BN binary composite were considered in this work. The design method of Taguchi and signal-to-noise (S/N) ratios analysis and main effects of the parameters were employed to randomize and optimize the levels of the SPS parameters. The microstructure and phase features of the samples sintered were analyzed by using a scanning electron microscope, an optical microscope and X-ray diffractometer respectively. Archimedes’ method, Vickers microhardness tester and a tribometer were used to evaluate the densification, microhardness and wear profiles of the samples. The most important parameter levels for optimum quality characteristics of the sintered composite were obtained at temperature, pressure, heating rate and holding time of 1000 °C, 30 MPa, 100 °C/min and 10 min, respectively. Ti6Al4V/h-BN composite approaching complete theoretical densification of 99.54%, microhardness value of 7.03 GPa, 1.66 GPa yield strength, 2.29 GPa ultimate tensile strength and wear rate of 8.075 x 10-6 mm3/Nm, respectively was produced with the optimized process parameters. The microhardness improved by approximately 216% and the wear rate improved by 97.8% of the Ti6Al4V alloy matrix. The improved microstructure, higher densification, mechanical and wear properties of the optimized composite were promoted by high sintering temperature and low heating rate which ensured adequate diffusional mass transport, achievement of refined grains, better pore filling and formation of solid matrix-reinforcement interfacial integrity.

We have studied tribological properties of conversion coatings, hard chrome on AISI 430 stainless steel, and zinc phosphate on AISI 1044 carbon steel. These substrates were chosen due to their extensive industrial applications. The goal of the present study is to improve the wear resistance of these substrates through the coatings. We performed nano-indentation and ball-on-disc tribometer experiments to study mechanical and tribological behavior of substrates and coatings. We find that when zinc-phosphate coating is applied to AISI 1044 steel, a new phase Zn2Fe(PO4)2·4H2O (phosphophyllite) is formed on the surface that increases the surface hardness. We further find that coefficient of friction decreases approximately by 8% due to hard-chrome coating on AISI 430 steel and by 48% due to zinc-phosphate coating on AISI 1044 steel under load and speed conditions applied in the present study. We attribute our findings to formation of: (1) an adhering layer of chromium in the case of chrome–steel contact, leading to chrome–chrome contact at the interface of test-specimen and counter-surface, and (2) a glossy layer at interface in the case of phosphate-steel contact, owing to the compaction and crushing of phosphate wear debris. Our wear studies show maximum reductions in specific wear rate to be around 80% and 89% for chrome and zinc-phosphate coatings, respectively. We note that adhesion and abrasion are the primary modes of wear for chrome and zinc-phosphate conversion coatings, respectively at the initial stage. However, adhesive wear switches to delamination wear at a later stage for hard-chrome coating.
