一、粉末渗锌简介黑色金属强度高,工艺性好,生产成本低,应用极为广泛,但其表面容易氧化锈蚀。为了弥补钢铁制品防锈能力之不足,人们采用油漆、电镀、热浸镀、刷镀、喷镀等防锈蚀措施以延长钢铁制品的使用寿命。这些措施,有其优点,也有其缺点:油漆、电镀制品的外表美观,但在室外使用时,寿命较短;热浸镀产量高,寿命长,但螺纹件不易镀好,对有弹性要求的零件不易控制,弹性降低比较严重;喷镀不受工件几何尺寸的限制,也不受工厂条件的限制,但劳动条件差,成本高,刷镀是一种新工艺,几 First, the powder infiltration Zinc Introduction Black metal high strength, good technology, low production costs, the application is extremely wide, but the surface is easy oxidation corrosion. In order to make up for the lack of anti-rust ability of steel products, people use paint, electroplating, hot dip plating, brush plating, spraying and other anti-corrosion measures to extend the service life of steel products. These measures have their advantages and disadvantages as well: the appearance of paint and electroplating products is beautiful, but their life time is short when they are used outdoors; the hot dip coating has high output and long service life, but the screw parts are not easy to be plated, Parts are not easy to control, reduce the more serious elasticity; thermal spraying is not limited by the geometric dimensions of the workpiece, but also not limited by the factory conditions, but poor working conditions, high cost, brush plating is a new technology, a few
