“…Although the compositions of the two coatings are similar, there are significantly lower Fe and Mn contents for the coating deposited at 1 kW, consistent with a lower level of dilution, hence promoting the formation of Cr 7 C 3 particles and hardening of the deposit [8]. The deposit on P91-1 was about 50 HV points higher than for the coating on P91-1.8 (Fig.…”

“…The deposit on P91-1 was about 50 HV points higher than for the coating on P91-1.8 (Fig. 3), this difference would be expected to substantially contribute the increase wear resistance [8]. The underlying HAZ was also marginally harder for the lower heat input (Fig.…”

Abstract. Stellite 6 was deposited by laser cladding on a P91 substrate with energy inputs of 1 kW (P91-1) and 1.8 kW (P91-1.8). The chemical compositions, microstructures and surface roughnesses of these coatings were characterized by atomic absorption spectroscopy, scanning electron microscopy and atomic force microscopy. The microhardness of the coatings was measured and the wear mechanism of the coatings was evaluated using a pin-onplate (reciprocating) wear testing machine. The results showed less cracking and pore development for Stellite 6 coatings applied to the P91 steel substrate with the lower heat input (P91-1). Further, the Stellite coating for P91-1 was significantly harder than that obtained for P91-1.8. The wear test results indicated that the weight loss for P91-1 was much lower than for P91-1.8. The surface topography data indicated that the surface roughness for P91-1 was much lower than for P91-1.8. The measurements of dilution and carbon content showed that P91-1 has lower dilution and higher concentration of carbon than P91-1.8. It is concluded that the lower hardness of the coating for P91-1.8, together with the softer underlying substrate structure, markedly reduced the wear resistance of the Stellite 6 coating and the lower hardness of the coating for P91-1.8 was due to higher level of dilution and lower concentration of carbon.

Effect of heat input on Stellite 6 coatings on a medium carbon steel substrate by laser cladding AbstractStellite 6 was deposited by laser cladding on a medium carbon steel substrate (MS) with energy inputs of 1. kW (MS 1) and 1.8. kW (MS 1.8). The chemical compositions and microstructures of these coatings were characterized by atomic absorption spectroscopy, optical microscopy and scanning electron microscopy. The microhardness of the coatings was measured and the wear mechanism of the coatings was assessed using a pin-on-plate (reciprocating) wear testing machine. The results indicated less cracking and pore development for Stellite 6 coatings applied to the medium carbon steel substrate with the lower heat input (MS 1). Moreover, the Stellite coating for MS 1 was significantly harder than that obtained for MS 1.8. The wear test results indicated that the weight loss for MS 1 was much lower than for MS 1.8. It is concluded that the lower hardness of the coating for MS 1.8, markedly reduced the wear resistance of the Stellite 6 coating.
