Introduction

Hard anodizing is an electrolytic treatment that forms a hard and usually thick aluminum oxide film, which is mainly used for engineering purposes. Hard anodizing can be used for cast or wrought aluminum and aluminum alloys. However, wrought aluminum alloys containing more than 5% copper and/or 8% silicon and Die-cast aluminum alloys require a special anodizing process. In order to obtain the best microhardness, wear resistance or low surface roughness characteristics Properties, choose low alloy content. Unless otherwise specified, workpieces are anodized after all heat treatment, machining, welding, forming and punching operations. The best results are obtained on the surface. Sharp contours should be processed into a radius of curvature not less than 10 times the predetermined thickness to avoid ablation or Peeling off. Hard anodizing typically results in a dimensional increase of 50% of the film thickness on a single surface. If necessary, the assembly should be Allowance for size increase. The film thickness is usually in the range of 25μm~150μm. Low thickness films (25μm) are sometimes used for various purposes, such as splines and threads; generally Thick films (50μm~80μm) are used for wear resistance or insulation; high-thickness films (150μm) are used for repair purposes, but the outer layer of the thick film tends to Very hard films reduce fatigue strength, a phenomenon that can be corrected by shot peening (see H.6) before hard anodizing. Hard anodizing results in increased surface roughness, which can be reduced by reducing alloy content or mechanical finishing. inhibition. Hard anodized films are generally used for. ---Resistant to abrasive wear or corrosive wear; ---Electrical insulation; ---Thermal insulation; ---Repair workpieces (repair parts that are out of tolerance due to machining or wear); ---Corrosion resistance (sealed film).
