EFFECT OF SURFACE NANO CRYSTALLIZATION AND THERMAL STABILITY OF 0Cr18Ni9 STAINLESS STEEL ON LOW TEMPERATURE NITRIDING BEHAVIOR
0Cr18Ni9不锈钢表面纳米化组织及其热稳定性对低温渗氮行为的影响

The composite structure with a nano crystallized surface and the matrix is very useful to obtain good comprehensive properties.Surface nanocrystallization is an important way to make a good combination of high hardness on the surface and good ductility at the center of materials,which not only modifies the surfacial properties,but also provides more channels to accelerate atoms to diffuse.In this work,a nanostructured layer was fabricated on a 0Cr18Ni9 stainless steel sheet surface by a supersonic fine part...
