Abstract To improve the corrosion resistance and wear resistance of piston rod, Fe-based coatings with martensite and ferrite structure were prepared on 45# steel by laser cladding. The phase compositions, microstructure and elements distribution of the coatings were characterized by X-ray diffractometer, scanning electron microscope and X-ray energy dispersive spectrometer. The microhardness and wear resistance of the coatings were tested by Vickers hardness tester and dry sliding friction wear tester. Furthermore, the corrosion resistance of laser cladding Fe-based coatings was studied by electrochemical workstation. The results show that the phase of laser cladding Fe-based alloy coating is mainly composed of α-Fe, Ni-Cr-Fe, γ-(Fe,C), Fe9.7Mo0.3. The main microstructure is martensite, ferrite and a small amount of residual austenite. The dendritic structure of coating is uniform, compact, without cracks or pores. The coating and the substrate are bonded metallurgically. The hardness and wear resistance of the coatings increase with increasing laser power. The average microhardness (HV) of the coatings at 2.4 kW is as high as 647.64 and the wear resistance is 9.37 times that of 45 steel. The wear mechanisms of the coatings are abrasive wear. The corrosion resistance of laser cladding Fe-based alloy coating firstly increases and then decreases with the increase of laser power. When the laser power is 2.0 kW, the coating has the best corrosion resistance, which is significantly higher than the commonly used carbon steel, stainless steel and electroplating hard for piston rods. It can replace electroplated chromium in related fields.
