摘要： An improved process is provided for forming a zinc-base alloy coating on an aluminum alloy profile, such as a tube or microtube used in the assembling and brazing of a heat exchanger which is suitable for automotive applications. The process of the present invention is a continuous, high speed coating technique which can utilize aluminum alloy profiles on which an aluminum oxide layer is present. Accordingly, the present invention encompasses an operation by which the aluminum oxide layer is removed so as to enable the zinc-base alloy to metallurgically adhere to the surface of the aluminum alloy profile. The process of this invention also is capable of closely controlling the thickness of the zinc-base alloy coating, such that a sufficient but minimal amount of coating is present to furnish corrosion protection as well as provide sufficient filler metal for a subsequent soldering or low temperature brazing operation.
摘要翻译：提供了一种改进的方法，用于在铝合金型材上形成锌基合金涂层，例如用于组装和钎焊适用于汽车应用的热交换器的管或微管。本发明的方法是连续的高速涂覆技术，其可以利用存在氧化铝层的铝合金型材。因此，本发明包括除去氧化铝层以使锌基合金能够冶金粘附到铝合金型材的表面的操作。本发明的方法还能够密切地控制锌基合金涂层的厚度，使得存在足够但最小量的涂层以提供防腐蚀保护，并且为随后的焊接或低温提供足够的填充金属钎焊操作。
