Diffusion of both aluminum and oxygen at the grain boundaries led to formation of new Al2O3 within the oxide layer.
In the diffusion zone,Fe diffused outwards from the substrate to the coating while Co diffused inwards from the coating to the substrate.One reason for this may be that Co forms substitution solid solution with Fe,which means that Co has high solution in the Fe base due to the fact that Co atomic number approaches that of Fe and their atomic radius difference is very small[10].Moreover, Ni diffused inwards from the coating to the substrate slightly in comparison with Co while Cr hardly took part in the diffusion 10μm obviously and mainly distributed in the coating.

It’s assumed gray black, thin of grain, slide of handle and had some hardness of water.

The interfaces are thought to prevent grain boundary sliding and dislocation propagation and, thus, contribute to the found significant enhancement in the hardness[4-5] ;On the contrary, the “incorrect” interfaces will reduce the interface binding force and reduce the hardness obviously[6].

The characterization of organic compounds present in material, sponge and powder calcinated has been checked by Fourier Transformed IR spectra using a FTIR Spectrophotometer in the wave number range of 4000 cm-1 to 400 cm-1, in transmittance mode.

A number of crack growth laws like the Paris law and the empirical formula of Forman were developed to predict the crack growth rate [2].
The finest mesh size used was 0.06mm, which is about two to three times of the grain size of 16MnR steel.

Although most lack the fine grain discrimination required for the retrieval task, the retrieval performance can be greatly improved by the combination of descriptors or some novel descriptors [7, 8].
Precision-recall plot: For each query model in class C and any number K of top matches, Recall is the percentage of models in class C accurately retrieved within the top K matches.
