D., Registration Date 12-06-2003 Organization Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine popup.description2 A technique of crack initiation іn а compact ceramic specimen under wedge loading was elaborated. The crack of defined length was initiated from the corner of the notch with an oblique front. Recommendations for increasing of the cyclic crack resistance of WC - Co hard alloy are suggested. The limits for the best chemical composition of the material were established. Influence of the cobalt phase content on fatigue and corrosion-fatigue resistance of WC - Co cermets was analyzed. It was found the corrosion environment with pH<4 caused hydrogen embrittlement of the cobalt phase and finally, drop in corrosion-mechanical characteristics of the material Product Description popup.authors popup.nrat_date 2020-04-02 Close
