    摘要： The present invention is to provide a method for laser welding different kinds of metals by which at least two types of metal members having mutually different laser reflection factor, are put one upon another and welded when the metal members are irradiated with lasers emitted in the superposed direction, comprising a process to put the first metal member on the second metal member, wherein the first metal member has a first laser reflection factor and the second metal member has a second laser reflection factor which is lower than that of the aforementioned first laser reflection factor, and the first and the second metal member are put one upon another through a metal layer and when irradiated with lasers, the aforementioned metal layer is more difficult to melt than the aforementioned second metal member. The method of the present invention further comprises a process in which lasers are irradiated from the aforementioned first metal member side. According to the aforementioned method, laser output which is sufficiently high to melt the first metal member having a high laser reflection factor, is irradiated from the first metal member side, so that this laser output is excessively high to melt the second metal member. However, the aforementioned metal layer acts as if it inhibits the laser input to the second metal member. Accordingly, abrupt laser input into the second metal member can be avoided, and the occurrence of scatter of the metal can be prevented so that an excellent joint condition can be obtained.

    摘要： A steel having good wear resistance which contains 0.55-1.10% of C, up to 2.0% of Si, up to 2.0% of Mn, 12.0-25.0% of Cr and particularly suitable as a material for piston rings or rocker arms. Further addition of 0.05-1.10% of Al to the above steel gives a steel improved in properties for spheroidization of carbides and uniformization of carbide particle size, leading to further enhancement of wear resistance. If required 0.20-2.0% of Ni may be added to the steels, whereby corrosion resistance, toughness and hardenability are improved. An addition of at least one of 0.2-3.0% of Mo, 0.1-1.5% of V and 0.05-0.70% of Nb to the steels improves high-temperature strength and surface hardness. The steel is surface treated by gas nitriding of the like in a surface area for sliding contact with an opponent member.
