随着科学技术的飞速发展,金属涂镀新技术在工业生产中的运用越来越广泛。近几年来,通过对内燃机车轴、孔类配件涂镀后的运用试验,证明涂镀层与原材质结合牢靠,两者机械性能也无太大的差异。尤其是不存在相对运动的过盈配合轴、孔配件,其运用安全可靠性就更大一些。 With the rapid development of science and technology, the new technology of metal coating is more and more widely used in industrial production. In recent years, through the use of diesel locomotive axles, holes coated after the application test to prove that the coating and the raw material with a solid combination of the two mechanical properties are not much different. In particular, there is no interference with the relative movement of the shaft, hole fittings, the use of safety and reliability is even greater.
