Generally, compound phases in alloys are harder than matrix and act as hard particles at dry wear condition. Such hard particles are helpful to reduce wear rate. However, the compound phases in alloys commonly act as cathodic phases in sulfuric acid media and can be sorted into two kinds. One is the strong cathodic phase that has low corrosion potential, such as Fe 3 C, Cr 23 C ...
Fe–N/Ti–N multilayers with different thickness of Ti–N layers were deposited on Si(111) wafer by using magnetron-sputtering technique. For comparison, Fe–N and Ti–N single-layered films were prepared under the same condition. The microhardness and the reduced modulus of the multilayer were measured by using a nanoindentor with a diamond tip (Berkovich) in conjunction with an atomic force microscope...
Fe-N/Ti-N magnetic multilayers with different thickness of Fe-N layers were deposited on Si (111) wafer by using magnetron sputtering technique. For comparison, Fe-N and Ti-N thin films were also prepared under the same conditions. Microhardness and reduced modulus of the multilayer were measured by using a nanoindenter with a diamond tip in conjunction with an atomic force microscope (AFM). Microfriction...
Corrosive wear behaviors of austenitic, ferritic and duplex stainless steel in sulfuric acid solution were investigated. Transmission electron microscopy with energy dispersive X-ray, scanning electron microscopy, microhardness tester, etc. were used to study the mechanism of surface deformation of stainless steel after corrosive wear tests. The result indicated that the corrosive wear rate of austenitic...
