日本日新制钢公司近来确立了在金属或玻璃粉末上包覆其它金属的复合粉末制造技术。由于抑制了包覆膜加热成型时的晶体长大,所以组织变细,模制品的强度、韧性得到提高。熔点有很大差异的金属也能制成复合粉末。预计今年春天安装试生产设备,开始出售样品。该公司确立的制法有两种:一种是
Japan’s Nisshin Steel Company has recently established a metal or glass powder coated with other metals composite powder manufacturing technology. Since the growth of crystals during the heat molding of the coating is suppressed, the structure is reduced and the strength and toughness of the molded product are improved. Metals with very different melting points can also be made into composite powders. It is estimated that the trial production equipment will be installed this spring and the samples will be sold. The company established the system of law in two ways: one is
