“…The test results of wear resistance agreed well with the microhardness. In general, higher hardness results in better wear resistance, as reported by the relevant studies on the laser cladding [37,38]. In another word, the cladding coatings showed a well matching of strength and toughness, otherwise the abnormality relationship between the hardness and the wear resistance would be obtained [39].…”

“…In all cases, the microhardness of the CL is higher than that of the substrate. As shown in Figure e, the microhardness of the HAZ near the CL–substrate interface is quite high (≈400 HV 0.2 ), which is attributed to the martensite laths formed during cooling . Moving from the CL–substrate interface to the substrate, the microhardness of the HAZ, which is composed of coarse bainite and ferrite (shown in Figure f), decreases sharply to 160 HV 0.2 .…”

Herein, single-pass laser-cladded 2205 duplex stainless steel is fabricated on the surface of Q235 carbon steel at different laser powers in the range of 1.7À2.7 kW. The relationships between laser powers and geometrical characteristics, microstructure, microhardness, and corrosion resistance of the cladded layers (CLs) are analyzed. The results show that with the increase in laser power, the width and height of the bead increase, and the dilution rate and depth of the molten pool also significantly increase. Furthermore, the shape of ferrite gradually transforms from coarse to slender and eventually turns into a discontinuous vermicular shape. It is found that the CL obtained at a laser power of 2.3 kW has higher average microhardness and exhibits better corrosion resistance than the other samples (%20 times better than that of the carbon steel substrate), with its corrosion potential and corrosion current density of À0.146 V and 0.13 μA cm À2 , respectively.

“…However, it is difficult to prepare a WC-reinforced composite coating with a uniform distribution, due to the different densities of the metal matrix and the WC particles. Mechanical vibration, ultrasonic, magnetic fields, and other auxiliary methods [13][14][15] can be used to control the microstructural evolution of ceramic-reinforced composite coatings, so as to achieve a uniform distribution of ceramic particles in the composite coating. However, it is still difficult to implement practical industrial applications for these methods, owing to the shortcomings of the equipment and the environmental constraints.…”

WC-reinforced Ni60 composite coatings with different types of WC particles were prepared on 304 stainless steel surface by laser cladding. The influences of spherical WC, shaped WC, and flocculent WC on the microstructures and properties of composite coatings were investigated. The results showed that three types of WC particles distribute differently in the cladding coatings, with spherical WC particles stacking at the bottom, shaped WC aggregating at middle and lower parts, with flocculent WC particles dispersing homogeneously. The hardnesses, wear resistances, corrosion resistances, and thermal shock resistances of the coatings are significantly improved compared with the stainless steel substrate, regardless of the type of WC that is added, and especially with regard to the microhardness of the cladding coating; the addition of spherical or shaped WC particles can be up to 2000 HV0.05 in some areas. Flocculent WC, shaped WC, and spherical WC demonstrate large to small improvements in that order. From the results mentioned above, the addition of flocculent WC can produce a cladding coating with a uniform distribution of WC that is of higher quality compared with those from spherical WC and shaped WC.
