金属喷镀是一种先进工艺,可使被喷镀工件的表面上复盖-适合于某种用途(如耐热、耐磨、耐腐蚀、美观等)的金属薄层,苏联及某些先进资本主义国家已将其应用在机械制造中,近两年来我国一机部有些工厂开始试用于机床修理业务中。57年铁道部拟将其应用到机车车辆制造及修理中去,但对金属镀层的基本性能,尚缺具体资料,故我院与南厂协作,对于镀层的若干基本性能(如硬度、结合强度、疲劳强度、含油性能、金相组织等),进行了初步试验,由于参加者学术水平及设备条件所限试验的很不全面,很不成熟,仅提出来供同志们参考并希指正。
Metallization is a state-of-the-art process that covers the surface of a workpiece being sprayed-a thin layer of metal suitable for a specific purpose (such as heat, abrasion, corrosion resistance, aesthetics, etc.), the Soviet Union and some advanced Capitalist countries have applied it to machinery manufacturing. In the past two years, some factories of a machine shop in China started trial operation in the machine tool repair business. In the past 57 years, the Ministry of Railways intends to apply it to the manufacture and repair of rolling stock. However, the basic performance of the metal coating is still lack of specific information. Therefore, our institute cooperated with the South Plant for several basic properties of the coating such as hardness, bonding strength, Fatigue strength, oil-containing properties, microstructure, etc.) conducted a preliminary test, due to the academic level of the participants and equipment limitations of the test is very comprehensive, very immature, only put forward for comrades reference and correct.
