Surface treatments for machined parts refer to many different methods including electronic plating coatings, 化学表面処理, およびいくつかの機械的表面処理, 等.
Surface treatments for machined parts enhance functionality, durability, corrosion resistance, and aesthetics.
The right choice depends on material, application, and environmental conditions.
Below are common surface treatment methods for machining precision parts for different kinds of materials:
1. Tool Steel Precision Machined Parts Surface Treatments
For common tool steel materials, 例えば, 鋼鉄, carbon steel, HSS, PMスチール, または超硬, there are different kinds of surface treatment for them.
- Carbon steel: Usually this kind material has a lower hardness and easily get rusty. So it may need a blackening surface treatment, or zinc plating, Nickel plating or Chrome plating.
- Common tool steel(including HSS): common tool steel has a medium hardness about 58~62 HRC. In order to enhance its durability and corrosion resistance, it usually have some PVD coatings, 例えば, Titanium Nitride (TiN), Titanium Carbonitride (TiCN), Diamond-Like Carbon (DLC), Aluminium Chromium Nitride (AlCrN). There are really many other this kinds if coating, they are TiC coating, AlCrTiN coating, TiALCN coating, CrCN coating, AlTiN coating, CrN coating, WC-C coating, TA-C coating, TiCTiN coating, 等.
- 炭化タングステン: For carbide material, itself has a very higher hardness around HRA 88~95. it usually has several specially coatings that can increase its use durability. These coatings are DLC, TA-C, WC-C.
2. Special Hydraulic Pressure and Mechanical Parts Surface Treatments
For some special hydraulic pressure and mechanical parts with threads, they may needs a hardened surface, but soft in the inner. There some times needs a nitriding, or nitro-carburizing, or called QPQ surface treatment.
3. Aluminum Machined Parts Surface Treatments
For アルミニウム合金 material, it usually has a kind of anodizing or hard anodizing surface treatment.
There are also some thermal & spray coatings and organic & polymer coatings. 例えば, PTFE (Teflon) Coating, powder coating and glass beads spray coating, 等.
Except for the above, there are also some mechanical surface treatments, 例えば: Burnishing, 研磨, そしてラッピング, 等. for some precision parts surface.
