Strucrture Analysis of High Hardness Alumina Sprayed Coating by Polarizing Microscope(Physics, Process, Instrument & Measurement)
Search this Article
By means of gas tunnel type plasma spraying, a high hardness alumina coating can be formed at a short spraying distance. The microstructure of such a hardness coating was observed by a polarizing microscope, and the mechanism of the formation of such hardness coating and the relation between the microstructure and Vickers hardness of this high hardness coating was discussed.
