Influence of Microstructure Evolution on Tribological and Corrosion Performances of QPQ-Treated 40Cr Steel
, and polarisation resistance of 24,500 Ω. Corrosion performance depends on overall surface integrity. Porosity morphology strongly influences this property. For 40Cr steel, the results show that surface properties are primarily determined by the quality of the compound layer's microstructure. Specifically, density, phase-composition stability, and defect control are more important than the commonly held view of layer thickness.
