为了用于深层渗碳,我厂研制了一种新型涂料,是由金属铜、氧化硅、氧化铝等高温氧化物和改性水玻璃配制而成。几年试验和生产使用表明其防渗性能良好。 1.试验结果在井式气体渗碳炉中,用甲醇和煤油于930℃下进行试验。对于20、20Cr、20CrMo,20CrMnTi和18Cr2Ni4W等钢皆有同样防渗效果。用柱套螺栓,圆棒、齿块等零件试验,涂料保护部位皆未渗入碳。并证明,涂层保护作用不随时间长短而变化,在洛阳矿
In order to be used for deep carburizing, our factory has developed a new kind of paint, which is made of metal copper, silica, alumina and other high temperature oxides and modified water glass. Several years of testing and production shows that its impermeability is good. 1. Test Results In a pit-type gas carburizing furnace, methanol and kerosene were tested at 930 ° C. For the 20,20 Cr, 20CrMo, 20CrMnTi and 18Cr2Ni4W other steel Jie Jie have the same anti-seepage effect. With stud bolts, rods, teeth and other parts of the test, paint protection sites are not infiltrated into the carbon. And prove that the role of coating protection does not change with the length of time in Luoyang ore
