摘要： An object of the present invention is to provide a sliding member which is coated a film having superior wear resistance, superior scuffing resistance and a superior property not to increase an amount of wear on an opponent material (an opponent attacking property). This object can be achieved by providing a sliding member coated by a Cr--V--B--N alloy film 4 on an outer surface 3 thereof. In this case, it is preferable that the Cr--V--B--N alloy film is formed through a physical vapor deposition, particularly ion plating, vacuum deposition, or sputtering. Further, it is preferable that V (Vanadium) content is within the range of 0.1-30 wt. % and the boron (B) content is within the range of 0.05-20 wt. %. Since the Cr--V--B--N alloy film 4 formed on the outer surface 3 of the sliding member has superior wear resistance, superior scuffing resistance and a superior opponent attacking property, it is possible to provide the sliding member which satisfies demand characteristics even when the sliding member are subjected to the harsh operating environments. Further, it is preferable that nitriding layer 5 is formed on a whole surface or at least an outer surface 3 of the sliding member, and the Cr--V--B--N alloy film 4 is covered on the nitriding layer 5.

摘要： The present invention is directed to a method of applying a magnetic thin film on a substrate by alloy electroplating in which the alloy content in the deposition is defined by an electric current density in the course of the plating operation. The magnetic thin film is superior in uniformity and formability on a complicated substrate. The method comprises the step of changing the electric current density from a low value to a high value, and vice versa at predetermined intervals during plating to laminate different alloy-content plated layers into a multilayer thin film, and improving the magnetic characteristics of the film by heat treatment.

摘要： A piston ring for use in an internal combustion engine. The piston ring includes a base body, a nitriding layer formed at an outer peripheral surface portion of the base body, and a composite Ni-B diffusion plating layer formed over the nitriding layer. The composite Ni-B diffusion plating layer has a thickness ranging from 0.5 to 20 micron meters. Since the nitriding layer is provided on at least the sliding surface of the piston ring, high durability of the piston ring can be attained because of the high wear resistivity of the nitriding layer. Further, since a Ni-Bi composite dispersion plating layer is formed over the nitriding layer, abnormal wearing due to scuffing is avoidable at an initial working phase because of the high scuffing resistance of the composite plating layer.
摘要翻译： 一种用于内燃机的活塞环。 活塞环包括基体，形成在基体的外周面部的氮化层和形成在氮化层上的复合Ni-B扩散镀层。 复合Ni-B扩散镀层的厚度为0.5〜20微米。 由于氮化层至少设置在活塞环的滑动面上，所以由于氮化层的高耐磨性，可以获得高活性环的耐久性。 此外，由于在氮化层上形成Ni-Bi复合分散镀层，因为复合镀层的耐擦伤性高，因此在初始加工阶段可避免由于磨损引起的异常磨损。
