摘要：

Medicine's prime concern is first not to harm, thereafter elongate and benefit lifespan. The vast technological advances of the last decade permit implementation of minimal invasive medicine in the different medical disciplines. Laparoscopic procedures and intubations, stents insertion and joint replacement had become commonplace in the operating rooms. Overcoming wear and frictional forces in order to elevate treatment efficiency and diminish unwanted side effects is now a rising challenge in designing new medical appliances. Here, two kinds of self-lubricating metal coatings with impregnated fullerene-like (IF) nanoparticles of W2 are presented: cobalt films deposited on NiTi substrate (foils and orthodontic wires) and nickel films deposited on orthodontic wires made of stainless steel. Tribological and mechanical tests provide strong evidence for the efficacy of the coatings in reducing the static and kinetic friction. It is concluded that the use of these self-lubricating coatings may have important impact on ubiquitous medical procedures. Copyright © 2010 Inderscience Enterprises Ltd.
