摘要： PROBLEM TO BE SOLVED: To provide a surface hardening method by which a layer of graphite or the like is formed on the surface of a base material, and further, the surface of the base material formed with the layer is rapidly heated and rapidly cooled to be quenched, thus the concentration of carbon in the surface of the base material is sufficiently increased, and the surface hardness of the steel having a low carbon content can be increased.
SOLUTION: Graphite powder 5 is scattered over the surface of a base material W made of a steel having a low carbon content, the surface is pressed by a press machine 6, and graphite powder 5 is crazed into the base material W, so as to form a graphite-crazed layer 4. Thereafter, the surface of the base material W with the graphite-crazed layer 4 formed is rapidly heated and rapidly cooled by a laser quenching apparatus. In this way, a white martensite layer 1 having a high carbon concentration is formed on the surface of the base material W, thus its surface hardness is increased.

摘要翻译：要解决的问题：提供一种在基材表面上形成石墨等层的表面硬化方法，此外，形成有该层的基材的表面被快速加热，迅速冷却淬火，由此能够充分提高基材表面的碳浓度，能够提高碳含量低的钢的表面硬度。解决方案：石墨粉末5散布在由低碳含量的钢制成的基材W的表面上，表面被压力机6挤压，石墨粉末5被切成基材W，从而形成石墨层4。此后，用形成的石墨层化层4的基材W的表面被激光淬火装置快速加热并快速冷却。以这种方式，在基材W的表面上形成具有高碳浓度的白色马氏体层1，因此其表面硬度增加。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method of diffusing or implanting an element into a metallic member by which a problem that a conventional modification method of a metallic member by element implantation is carried out only in a limited specific purpose and lacks versatility such as homogeneous alloying is solved. SOLUTION: A hard particle comprising an element to be diffused or implanted which is harder than a metallic member to be treated is driven into the metallic member at a high speed to diffuse or implant the element to be diffused or implanted from the contact interface between the driven hard particle and the metallic member.

摘要： PROBLEM TO BE SOLVED: To realize the countermeasure of erosion resistance excellent in the durability and in a low cost to various kinds of metallic materials. SOLUTION: At the time of producing a sleeve for a die casting machine by pouring molten metal for constituting a sleeve into a mold 3 and solidifying, a diffusion layer diffusing different kind of molten metal to the molten metal is formed in the inner wall of the sleeve by reaction between the molten metal constituting the sleeve and the mold 3. Further, the erosion resistance layer mainly containing carbide, nitride, boride, etc., is formed by reacting the diffused metal and carbon contained in the molten metal, applying carburizing treatment at the same time of formation of the diffused layer to the inner wall of the sleeve or applying nitriding treatment or boriding treatment.

摘要： PURPOSE:To remarkably improve the efficiency of carburization with a solid carburizer by blowing gaseous NH3 or H2 into a vessel contg. a steel to be carburized. CONSTITUTION:A charcoal-base solid carburizer and a steel to be carburized are put in a vessel and heated. During the heating, gaseous NH3 or H2 is blown into the vessel. For example, a steel to be carburized such as SNC22 or SKD11 is wrapped in a solid carburizer consisting of about 70% charcoal and about 30% barium carbonate, they are heated at about 950 deg.C for about 6hr under blown gaseous NH3 or H2 and then hardening is carried out. The steel to be carburized is not oxidized and a carburized layer more than twice as thick as a carburized layer formed by a conventional method (hermetically sealed system), is obtd.
