Abstract: High velocity arc spray (HVAS) is investigated compared
with those of regular arc sprayed coatings. The wear properties of three
HVAS coatings are also tested. Results show that HVAS coatings have a
better comprehensive mechanical properties and quality. For the HVAS
coatings, the adhesion strength and the relative wear resistance
increase respectively by 40% and more than two times than those of
regular arc sprayed coatings.
Key words: High velocity arc spray Microstructure Properties
