Development of effective green lubricants for industrial drilling systems in aggressive environments
DownloadSpring 2024
In drilling systems used in the oil and gas industry, drilling equipment often encounters critical problems which could result in irreparable damage to metallic equipment. Chemical and physical interactions at the contact between different parts, such as drill bits, drill strings with well walls...

Studies on the improvement in wear resistance of WC-Co composites by adding a pseudo-elastic TiNi phase and relevant issues
DownloadSpring 2012
In this study, pseudo-elastic TiNi alloy was added as a second phase to the Co matrix of WC-Co composite, which has found many applications in forms of coating, hardfacing overlay and bulk against wear. It was demonstrated that the added TiNi phase markedly enhanced the wear resistance of...
