원재료 및 구성 카바이드 인서트
Carbide inserts are primarily composed of tungsten carbide, a compound formed from tungsten and carbon. Here’s a breakdown of their typical raw materials and composition:
| 구성 요소 | 역할 | Percentage (Typical) |
|---|---|---|
| 텅스텐 카바이드(WC) | 경도와 내마모성을 제공합니다. | 70-97% |
| 코발트 (Co) | Acts as a binder to hold the carbide grains together. | 3-20% |
| 티타늄 카바이드(TiC) | Enhances heat resistance and toughness. | 0-10% |
| 탄탈 탄화물(TaC) | Improves high-temperature stability. | 0-5% |
The exact mix depends on the insert’s intended application, balancing hardness, toughness, and resistance to thermal and mechanical wear.
Production Process Flow of Carbide Inserts
Ever wondered how these tiny marvels are made? The process is intricate and ensures every insert meets exacting standards.
- 분말 준비
Tungsten carbide, cobalt, and other additives are mixed into a fine powder. - 압축
The powder is pressed into a mold to form the desired insert shape using high pressure. - 소결
The compacted shapes are heated to high temperatures (around 1400°C) to bind the particles, creating a solid, dense material. - 연삭 및 성형
The sintered inserts are ground into precise geometries using diamond-tipped tools. - 코팅
Depending on the application, inserts may be coated with materials like titanium nitride or aluminum oxide. - Inspection and Packaging
Each insert undergoes rigorous quality control to ensure dimensional accuracy and performance before being shipped.
