Conclusions
-
1.
Using the test technique described it is possible to evaluate the shear strength of a tungsten coating (but not the adhesion of the coating to a substrate).
-
2.
It is shown that spraying range exerts a dominant influence on the shear strength of deposits.
-
3.
The effect of microstructure and residual stresses in coatings on the shear strength was determined.
