Study on External Grind-Hardening Experiments and the Analysis of Hardening Effects for 40Cr Steel

Abstract:

External grind-hardening is a new technology combing grinding and quenching. Hardening tests are carried out according to 3-level and 3-factor orthogonal method for 40Cr steel, and metallographic observation and hardness measurement are put forward. Martensite is found in the surface layer structure, which hardness reaches HV647.4~719.4 and depth is about 0.22~1.1mm. The practicability of the new technology is confirmed. Orthogonal analysis is proceeded successively for the acquirements of influencing pattern and significance of factors based on the hardening results.
