Surface treatments for machined parts refer to many different methods including electronic plating coatings, химическая обработка поверхности, и некоторая механическая обработка поверхности, и т. д..
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, например, сталь, carbon steel, HSS, PM Steel, или карбид, 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, например, Titanium Nitride (TiN), Titanium Carbonitride (Тикн), Diamond-Like Carbon (DLC), Aluminium Chromium Nitride (АлКрН). 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, и т. д..
- Карбид вольфрама: 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 Алюминиевый сплав material, it usually has a kind of anodizing or hard anodizing surface treatment.
There are also some thermal & spray coatings and organic & polymer coatings. Например, ПТФЭ (Teflon) Coating, powder coating and glass beads spray coating, и т. д..
Except for the above, there are also some mechanical surface treatments, например: Burnishing, полировка, и лапки, и т. д.. for some precision parts surface.
Итак, там все о surface treatments for machined parts. Надеюсь, наше введение будет для вас полезным..
