Microhardness, depth profile and wear mechanisms were investigated by means of MVK H12, TALYSURF6, XPS and microscopy.

microhardness of coatings increased with increased spraying distance linearly.

The microhardness treated by plasma heat treatment is notably improved, and the wear resistance and operating life increase obviously.

Microstructure and surface morphology of the oxynitriding layers were studied by SEM, XRD, microhardness tester and digital camera.

The microhardness of the processed zone is lower than the cast metal, but further uniform microhardness is observed in the processed zone.

The measured values of microhardness were calculated using mathematical statistic method.

The copper deposit also represented higher microhardness and better corrosion resistance.

The microhardness distribution on cross section at both sides of the interface changed smoothly.

The microstructure, microhardness and wear resistance of compound region were observed and measured.

The microhardness and surface roughness increase with the shot peening intensity increase.

Vickers hardness testing of resistance spot, projection and seam welds (low load and microhardness).

The microhardness and wear resistance of the implanted layer were determined.

The microhardness of twin spot laser welded joint is higher than that of single spot laser welded joint, but lower than that of base metal.

Further increase of aging temperature and time could lead to the growth of the secondary phase and thus decrease of microhardness.

The hardness of the coating was tested using vickers microhardness tester.

On the basis of the microhardness variation, the HAZ is divided into five subregions .

And in the same condition, the microhardness and wear-resistance of plastic artificial tooth descended slightly.

The depth and microhardness of strengthening layer is increased, With increasing working elastic current, but the microha. . .

The microhardness of weld metal zone, HAZ and base metal decrease in totality after heat treatment.

Both FZ and HAZ have higher microhardness than the base metal has, and microhardness in fusion centre zone is the lowest.

Metallic and other inorganic coatings - Vickers and Knoop microhardness tests.

But the microhardness of the weld bead after heat treatment reduces by 60 HV, compared with origin welded joint.

For the nickel deposit, microhardness increased 90% and tensile strength increased 130%.

The surface microhardness without cutting fluid is higher than that with cutting fluid.

However, the microhardness of transition region declines sharply and the microhardness of matrix is very low.

The results show that a metallurgically bonded coating is obtained, and the microhardness and wear resistance of the substrate. . .

The bigger values of microhardness and microbrittleness is, the more bump-prone property the coal seam has.

The layer is smooth with higher microhardness, corrosion and bonding strength by using the proper process.

The microstructure, composition of plating, microhardness, deposited rate and so on were discussed.
