Experimental Study of HVOF Coating of WC- 10CO-4CR on Mild Steel Plate

The aim of this book is to enhancing the material properties of the base metal by coating with powder metal. In this study we used the metal powder of WC-10Co-4Cr. The HVOF spray method is selected in this experimental study and the mild steel plate was taken as the base metal. Basically four parameters have been used, they are- oxygen flow rate, LPG flow rate, standoff distance, powder feed rate. Various testing measures have been taken for the final result. Micro-hardness test, porosity level, optical microscopy, SEM image analysis were performed at testing centre. After these analyses it was found that the hardness increased at high level and the porosity level is up to 1%.
