摘要：
Coatings containing stick borides were produced by laser surface alloying of Ti-6Al-4V with powder mixtures of boron and titanium, The test results indicated that the coatings have high microhardness, excellent wear resistance and are more resistant to oxidation than the original sample. The size and the morphology of the borides vary with laser scanning speed, which have an effect on the properties of the coatings. (c) 2008 Elsevier B.V. All rights reserved.
