: It is very interesting , You said that with increasing fuel gas flow amorphous phases quantity of WC-12Co coating increase and decrease wear resistance , but at the same time coating porosity decrease. So, how to find optimum parameters of gas flow?
: And I got that by increasing heat treatment temperature from 20C up to 600C microhardness of WC-12Co coating a little bit increase (5-10 percent) How to explain it?
