铅合金制件表面黑化处理,可以起到提高热量辐射传递、防腐、装饰等作用。目前在许多科学研究和生产过程中提出这种要求。例如高速旋转体在真空中的散热,太阳能的吸收罩,以及超高速离心机转子的表面处理,电气开关按键的防腐蚀等都需要在铝
Lead alloy surface blackening treatment, can play to improve the heat radiation transfer, corrosion, decoration and so on. This requirement is presently in many scientific research and production processes. For example, high-speed rotating body in the vacuum heat, solar energy absorption hood, as well as ultra-high speed centrifuge rotor surface treatment, anti-corrosion of the electrical switch button and so on are required in the aluminum
