Low friction and wear resistant coatings have a long history of successful applications in industry. It has long been hoped that these coatings, especially diamond-like carbon (DLC), could also be used successfully in load-bearing joint implants, extending implant life time considerably. However, despite several medical studies carried out so far, no regular DLC-coated implants are available on the...
The aim of this work is to investigate the influence of surface precleaning procedures prior to deposition of hydrogenated amorphous carbon films onto stainless steel. In industrial coating processes the substrates are first degreased and then Ar-ion sputter-cleaned in the deposition chamber just prior to film deposition. This sputter cleaning, which removes the native surface oxide layer as well...
