1.浸渗技术及其应用 微孔渗漏现象是机电产品常见缺陷。黑色金属铸件如此,有色合金压铸件和粉末冶金烧结件更为严重。随着机电产品承压能力提高,由于渗漏造成废品的比例越来越大。据统计,铸件的废品率为:铸钢件为 10％～20％,铸铁件为 6％～10％,铸铜件为 5％ 1. Infiltration technology and its application Micro-porous leakage is a common defect of mechanical and electrical products. Ferrous metal casting In this way, non-ferrous alloy die-casting and powder metallurgy sintered more serious. As the pressure-bearing capacity of electromechanical products is increased, the proportion of waste products caused by leakage is getting larger and larger. According to statistics, the reject rate of castings is 10% -20% for castings, 6% -10% for castings, 5% for castings,
