    • PROBLEM TO BE SOLVED: To improve low temperature gas carburization processes to achieve faster, more economical operation though it can achieve hardened stainless steel products with superior corrosion resistance, and to provide a modified low temperature gas carburization process for case hardening stainless steel and other ferrous-based materials which allows faster carburization than possible in the past and thereby reduces the overall cost of such procedures.SOLUTION: The modified low temperature case hardening processes are concretely a process for enhancing the surface hardness of a workpiece by gas carburization comprising contacting the workpiece with a carburizing gas at an elevated carburizing temperature sufficient to promote diffusion of carbon into the workpiece so as to form a hardened case with a prescribed thickness without the formation of carbide precipitates. The instantaneous rate of carburization is more reduced during the carburization in such a manner that the swift carburization is promoted in the early stage of the carburization, and simultaneously, the formation of carbide precipitates in the latter stage of the carburization is avoided.
    • 要解决的问题:为了改善低温气体渗碳工艺,实现更快,更经济的操作,尽管它可以实现具有优异耐腐蚀性的硬化不锈钢产品,并为外壳硬化不锈钢提供改进的低温气体渗碳工艺 和其他铁基材料,其允许比过去更快的渗碳,从而降低了这种方法的总体成本。 解决方案:改进的低温表面硬化方法具体地是通过气体渗碳提高工件的表面硬度的方法,包括使工件与渗碳气体接触,所述渗碳气体的升高的渗碳温度足以促进碳扩散到工件中, 以形成具有规定厚度的硬化壳体而不形成碳化物沉淀物。 在渗碳过程中渗碳时间的瞬时速率在渗碳早期促进快速渗碳的同时,也可以避免渗碳后期的碳化物析出物的形成。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a new article of manufacture that is in the form of an article made of a chromium bearing nickel or ferrous based alloy and that is selectively case hardened over a surface area that is less than the entire area of the article without the formation of carbides. SOLUTION: A selectively case hardened steel article by low temperature carburization includes a body made of a chromium-bearing nickel or ferrous-based alloy (for example, stainless steel), a first portion of the body having a first hardness characteristic, and a second portion of the body having a second hardness characteristic; the second portion being less than the entire body and substantially free of carbides. One method for selective case hardening by low temperature carburization includes the steps of: applying a carbon blocking mask over surface areas of the article that are not going to be carburized; activating those surface areas that are to be carburized; diffusing carbon into the activated surface areas at a temperature below which carbides readily form; and removing the carbon blocking mask.

    • PROBLEM TO BE SOLVED: To provide a method for case hardening a chromium bearing nickel or ferrous based alloy, for example stainless steel, article.
      SOLUTION: A low temperature case hardening process relates to processing techniques for articles of stainless steel and other alloys such as, for example, tube coupling ferrules, more particularly relates to processes for case hardening such articles substantially without the formation of carbides. The method for case hardening a chromium bearing nickel or ferrous based alloy, for example stainless steel, article includes the steps of activating the surface of the article and carburizing the activated surface at a temperature below that temperature which would promote the formation of carbides. In one embodiment, the surface is activated by disposing a layer of iron over the surface of the article.
