Pintakarkaisumenetelmä
Pintakarkaisumenetelmä, also known as surface hardening or case hardening, is a heat treatment process used to improve the surface hardness of steel parts while maintaining a tough and ductile core. This method is crucial for components that experience high wear and abrasion, such as gears, bearings, and cutting tools. The primary goal is to create a hardened surface layer, or "case," which is significantly harder than the underlying material.
Several techniques fall under the umbrella of pintakarkaisumenetelmä. Carburizing is a common method where steel is
The depth of the hardened case, its hardness, and the overall metallurgical structure are controlled by factors
