Abstract

Cracks-free wear resistance coatings are fabricated by laser surface nitriding pure titanium andTi-6Al-4Vin an open system. The titanium nitrides which are formedin situin the top layers of the samples are undeveloped dendritic, and thus reduce the possibility of the crack formation in the coatings during laser processing. The test results show that the nitride layers have higher microhardness and more resistant to sliding wear compared to the as-received sample.
