Hi Vrakpant
Quote:I need a coating that can withstand elongation at fracture of 15%. The enviroment contains alot of NaCl (10%) so low alloys are not to be considered.
Well I don't think any thermal spray coating will come any where near 15%.
What is the application for coating?
Quote:Does anybody know the young's modulus for HVOF sprayed tungsten carbid e.g ?
D-Gun WC/Co type coatings claimed:
Modulus of rupture: ~ 350 - 700 MPa
Modulus of Elasticity: ~ 150,000 - 200,000 MPa
I think HVOF will be in same sort of ball park.
