ＣｅＯ２对ＮｉＣｒＢＳｉ激光熔敷层组织和性能的影响田保红吴磊郑世安（洛阳工学院）杨院生（中科院金属研究所）在金属材料表面进行激光熔敷以获得特殊表面性能的研究已取得很大进展，并已用于生产，其中以镍基自熔合金应用最广［１～４］。但目前仍存在敷层与基体结合...
The effect of cerium oxide on the microstructure and wear,friction and corrosion properties of laser cladding NiCrBSi alloy coating on steel 40Cr has been studied. The results show that the comprehensive interaction effects of dendritic crystal finery,antifriction and wear resisance have been taken place by means of adding 8 mass percent of CeO 2 to laser cladding NiCrBSi alloy coating. The interaction mechanism of CeO 2 in laser cladding coating is also discussed.
