工件上形成铁碳高硬度合金膜的新方法日本扶桑化学工业公司与大阪市立工业研究所，共同开发了在常温下简易地形成铁－碳高硬度合金膜的新工艺。以往，一般是烧结金属粉末等，在工件上成形各种合金薄膜，但由于高温处理而需要相应的设备。新方法是从含有硫酸亚铁与碳酸水溶... A new method of forming a high-iron-carbon alloy film on a workpiece Japan’s Fuso Chemical Co., Ltd. and Osaka City Institute of Industry jointly developed a new process for easily forming an iron-carbon high-hardness alloy film at room temperature. In the past, generally, sintered metal powders and the like were used to form various alloy films on workpieces, but due to the high temperature treatment, corresponding equipment was required. New method is from containing ferrous sulfate and carbonic acid ...
