Case Depth Hardness
Applied Technical services’ case depth hardness tests evaluate the mechanical properties of materials. Hardness tests can help predict a material’s performance in a specific environment or application, allowing manufacturers to make informed decisions regarding the intended purpose of a product or material.
Understanding Case Depth
Case depth refers to the thickness of a material’s hardened layer. Case depth is determined using mechanical, chemical, or visual methods. There are two types of case depth: effective and total case depth.
Effective Case Depth
Effective case depth refers to the distance between a part’s surface and a specific hardness.
Total Case Depth
Total case depth refers to the total distance nitrogen, carbon, or both are diffused into a material
Understanding Case Hardness
Case hardness is the outer surface of a material that is substantially harder than the material’s core. Case hardening is a that process hardens the surface of ferrous materials such as carbon steel, cast iron, and copper.
Common Case Hardening Methods
Induction Hardening
Induction hardening is a heat treatment used to enhance the material properties of materials. Advantages include:
- Increased wear resistance
- Increased strength
- Increased fatigue life
- Minimal warpage
- Cost-efficient
Carburizing
Exposure to heat and carbon strengthens the material’s surface hardness. Advantages include:
- Increased wear resistance
- Increased strength
- Increased fatigue life
- Minimal warpage
- Cost-efficient
Gas Nitriding
Exposure to heat and atomic nitrogen increases the resistance and hardness of the material. Advantages include:
- Increased wear resistance
- Increased strength
- Allows post-application machining
- Cost-efficient
- Minimal warping
