【 摘 要 】

This study concerns droplet phase influence and process parameters influence (laser radiation power, oblique deposition, residual oxygen pressure, etc.) on morphology and composition of the coating and formation of oxides in the coating during pulsed laser deposition of Titanium on inner surface of tubes. It is shown that droplets in the coating in the presence of residual oxygen significantly affect the composition of Ti-coatings.
