日本神户钢铁厂最近开发了铝铬合金镀层钢板,其耐腐蚀性为过去镀铝钢板的20倍。它是通过连续真空蒸镀法制得的,即在真空容器内使铝铬原子蒸发而再沉积形成镀膜。铝铬合金镀层目前在宽150mm的钢板上获得成功,该钢铁厂正加紧进行宽幅钢板的铝铬合金镀层研究,以便早日进入实用化、商品化。该镀层是在真空容器中,将电子射线分别照射到铝和铬上使其蒸发,并在钢板上形
Kobe Steel Works of Japan recently developed the aluminum-chromium alloy coated steel plate, its corrosion resistance is 20 times that of the past aluminum plated steel plate. It is obtained by a continuous vacuum evaporation method, that is, in a vacuum vessel so that the aluminum-chromium atoms evaporated and then deposited to form a coating. Aluminum-chromium alloy plating is currently on the success of 150mm wide steel plate, the steel plant is stepping up the wide-plate aluminum-chromium alloy coating research, so as soon as possible into the practical, commercialization. The coating is in a vacuum vessel, the electron beam were irradiated on the aluminum and chromium to evaporate, and the shape of the steel
