The adhesion of thermally sprayed coatings is an important subject for engineers applying thermal spray pro-cess. The single pendulum impact scratch test is the most popular method in the tribological in progress of modified sur-faces of materials.

The key of evaluation for thermally sprayed coatings is the sheer strength of coatings obtained in the test. The results show that the test method is reproducible, reliable and easy to perform, and does not require expensive equip- ment. the proposed proposed in the test method for evaluating the adhesion of coatings is more reliable and realistic thanothers.
