高技术的迅速发展对金属材料提出了更高的要求,为了适应市场变化的需要,许多国家正在调整传统的产品结构,特种金属和合金不断问世,普遍金属材料的产量逐年减少。超耐热不锈钢是近几年国外竞相发展的新型结构材料,广泛用于航空发动机和动力设备,去年日本石川岛(禾番)磨重工业公司用喷溅法取代轧压技术将合金覆盖在铜基片表面,形成厚50微米的覆盖层,并降低生产成本30％。由美国RSM公司研制的彩色不锈钢已于去年大量生产,目前可供呈绿、金黄、古
Rapid development of high technology has set higher requirements for metal materials. In order to meet the needs of market changes, many countries are adjusting their traditional product mix. Special metals and alloys are advancing constantly, and the output of common metal materials is decreasing year by year. Super heat-resistant stainless steel is competing in recent years, the development of a new type of structural materials, widely used in aircraft engines and power equipment last year, Japan Ishikawajima (Wo Fan) mill heavy industry by sputtering instead of rolling technology to cover the alloy copper alloy The surface of the sheet forms a coating of 50 μm thick and reduces the production cost by 30%. Color stainless steel developed by the United States RSM company in mass production last year, currently available for green, golden, ancient
