“…In addition, again due to the porous structure of the powder, most of the laser energy is absorbed by the preset layer, thus ensuring that excessive melting of the substrate does not occur. Many researchers have studied the effect of Ni-based powder alloying on aluminum alloys [6,20]. However, there are few studies on the effect of Ni-based powders on the laser alloying of thin aluminum alloy sheets in the literature.…”

In this study, a laser surface alloying method is used to alloy 1.8 mm thick 6061 aluminum alloy sheets with Ni alloy powder. The mechanical properties of the resulting alloy are investigated. The experimental results show that, following laser surface alloying, a crack-free zone can be generated but some fine porosity appears. The hardness and the wear properties of the laser alloying specimens are superior to those of the Al-matrix. A hardness of 539 HV is achieved, which is five times greater than that of the Al-matrix. As a result, the laser alloying specimens exhibit excellent wear properties and higher sliding wear distances and speeds compared to those of the Al-matrix, whereby the sliding distance is greater by up to eight times and the sliding speed is increased four-fold.

In this study, the CoCrAlYTa-10%Al2O3 coatings were prepared by the high-velocity oxygen-fuel (HVOF) spraying. A series of ball-on-disk sliding wear tests were conducted to evaluate the tribological properties of the coatings at different temperatures (25 °C, 200 °C, 400 °C, and 600 °C). The results showed that the average coefficients of friction (COFs) of the CoCrAlYTa-10%Al2O3 coatings were lower than that of H13 steel at different temperatures. The average COFs of the CoCrAlYTa-10%Al2O3 coatings and H13 steel both decreased with increasing temperature. The wear rate of the CoCrAlYTa-10%Al2O3 coatings increased first and then decreased. The microhardness of worn surface of the CoCrAlYTa-10%Al2O3 coatings increased with increasing temperature, while the microhardness of worn surface of H13 steel at 25 °C and 200°C was higher than that at 400 °C and 600 °C. The wear mechanism of the two materials was mainly abrasive wear. The tribofilms were formed on the worn surface of the CoCrAlYTa-10%Al2O3 coatings, which had a good protective effect. Due to thermal softening and low binding strength of debris, it was difficult for H13 steel to form the tribofilms. The wear rate of H13 steel was much higher than that of the CoCrAlYTa-10%Al2O3 coatings at 400 °C and 600 °C, indicating that the high temperature wear resistance of the coatings was much better than that of H13 steel.

“…Adding soild particles or fibers to plating or chemical bath, make these deposited with base material and form composite coatings, which is an important surface strengthening means that were researched in past two decades [1,2]. As important surface strengthening materials, Ni-base alloy coatings have been successfully applied to machine parts in mechanical engineering because of their excellent properties such as high hardness, high bonging strength, anti-wear and corrosion resistance [3][4][5][6]. The SiC particle exhibit excellent properties of high hardness, anti-wear and high temperature resistance, adding it to Ni-Co alloy may improve friction and wear properties of coatings, extend their service life and range of applications [7].…”

Ni-Co/SiC composite coatings embedded with different sizes of micron-Sic particles were prepared on the surfure of 45 carbon steel through electrochemical deposition. The effects of size of SiC particles on the microstructure, the hardness and tribological properties of the composite coatings were investigated. The results show that the decrease of the size may increase the hardness, make microstructure closer and greatly improve their wear resistance. The Ni-Co/SiC(W7) coating exhibit better integrated properties, its hardness was HV505, 20 percent higher than Ni-Co alloy coating, and its wear rate was only 1/5 of the Ni-Co/SiC(W40) coating. The wear mechanisms of the coatings are mainly plastic deformation with slight adhesive wear.
