文摘

Long duration immersion tests reveal inhomogeneous weight losses. The weight loss for different coatings are well corroborated with the coating defects. Chemical and micro structural analysis elucidates the reason behind the in homogeneous performance of different type of cold sprayed coatings. In cold sprayed titanium, formation of oxide along the inter-splat boundary hinders the aggressive attack of the medium.
