Description

一种活塞火力岸至顶面范围微弧氧化工艺装备A kind of micro-arc oxidation process equipment ranging from piston fire power bank to top surface

技术领域technical field

本发明属于微弧氧化工艺用夹持设备技术领域，具体涉及一种活塞火力岸至顶面范围微弧氧化工艺装备。The invention belongs to the technical field of clamping equipment for a micro-arc oxidation process, and in particular relates to a micro-arc oxidation process equipment ranging from a piston fire power bank to a top surface.

背景技术Background technique

活塞是发动机的核心零件之一，其顶部更是构成燃烧室的主要部分。由于活塞在高温高压高负荷下工作，因此对于活塞的要求相对较高，需要有足够的强度、刚度以及较小的质量，以保证小的惯性力。但其主要材质为铝合金，刚度和耐蚀性无法保证工作过程的顺利进行，所以必须对活塞火力岸距顶面指定范围进行强化处理。而目前对活塞表面处理最常用的是阳极氧化工艺，但阳极氧化工艺所用的电解液为酸性，环保型较差。微弧氧化工艺作为一种绿色表面处理工艺，是对活塞进行阳极氧化工艺的一种很好替代方式。但现有针对该工艺的设备还较少，不能实现对活塞的批量化处理。The piston is one of the core parts of the engine, and its top is the main part of the combustion chamber. Since the piston works under high temperature, high pressure and high load, the requirements for the piston are relatively high, and it needs to have sufficient strength, rigidity and small mass to ensure a small inertial force. However, its main material is aluminum alloy, and its stiffness and corrosion resistance cannot guarantee the smooth progress of the working process, so it is necessary to strengthen the designated range of the piston fire bank from the top surface. At present, the most commonly used method for surface treatment of pistons is anodizing process, but the electrolyte used in the anodizing process is acidic, which is not environmentally friendly. As a green surface treatment process, the micro-arc oxidation process is a good alternative to anodizing the piston. However, the existing equipment for this process is still relatively small, and the batch processing of pistons cannot be realized.
