Treating method for surface of brazer aluminum product
专利汇可以提供Treating method for surface of brazer aluminum product专利检索，专利查询，专利分析的服务。并且PURPOSE:To form a rigid carbon coating on the surface of an aluminum product with feasible workability by ion bombarding the high temperature clean aluminum product completed in a vacuum brazing work immediately in a low pressure gas containing hydrocarbon gas by means of glow discharge. CONSTITUTION:After the surface of an aluminum product such as, for example, an aluminum heat exchanger assembly 14 is cleaned in a pretreatment chamber 1 reduced under pressure, it is fed to a vacuum brazing chamber 2 and brazed. It is then immediately fed into an ion plating chamber 3. Valves 9, 10 are opened to introduce hydrobarbon such as methane or the like and argon. Then, several kV of DC voltage is applied between anode plates 11, 11 and floor surface by a high voltage power supply 12 under vacuum such as 10 Torr or the like. Then, glow discharge occurs between the high temperature heat exchanger assembly 14 and both the anode plates 11, 11 to decompose the metane into carbon and hydrogen to be ionized. Thus, the ionized carbon 15 collides with the assembly 14 to rigidly braze it.，下面是Treating method for surface of brazer aluminum product专利的具体信息内容。
