The wear behaviour of different metallic bond alloys tested in a modified B611-13 test in an acidic, neutral and alkaline media

The abrasive and adhesive wear behaviour of metallic bonds can be significantly affected by varying pH values the attacking medium. However, knowledge about value influence on diamond impregnated bits used in core drilling industry is still limited. One recent publication shows advantage modifying a standard ASTM B611-13 test to investigate segment bond material neutral regime (pH7). This study mainly focuses effects surrounding media tribological using an acidic, alkaline slurry. emulates more aggressive conditions for segments mining as well construction industry. at which such operate differ from pH2 up pH13. present work studies two modified arrangement 4 m/s sliding speed different values. tested specimens are investigated with regard their change mass microstructure interface zone. results reveal significant system.
