Effect of Mo ion-implantation on the adhesion of diamond coatings
Mo离子注入对金刚石涂层附着性能的影响

Diamond coatings were deposited on the cobalt-cemented tungsten carbide(YG6) substrates, which have been implanted with Mo ions, by microwave plasma CVD(MPCVD) method.The effect of ion-implantation on the adhesion of diamond coatings was studied. The results showed that the chemical compositions of cemented carbide substrate surfaces change obviously after Mo ion-implantation; and the adhesion strength between the CVD diamond coatings and the substrates implanted with Mo ions in proper concentration is improved remarkably.
