However, the grinding may change the properties of coating. In this study, effects of the grinding process on the porosity content, residual stress, microhardness, and adhesion and cohesion strength of the high-velocity oxy-fuel WC–10Co–4Cr coatings are investigated.
Grinding aids reduce the adhesion forces between particles without a negative impact on the stability of the material bed and fluidisation. In ball mills, where the grinding time is longer than in a VRM, excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill.

Jan 09, 2007· An anaerobic adhesive remains liquid until it is isolated from oxygen in the presence of active metal ions, such as iron or copper. For example, when an anaerobic adhesive is sealed between a nut and a bolt on a threaded assembly, it rapidly cures, or hardens, to form a tough, crosslinked plastic with tenacious adhesion to many metals.
In the process of grinding titanium rods, there is a serious grinding wheel adhesion, the grinding force and the grinding temperature are very high, so the grinding burns and cracks occur simply. When the titanium rod is ground with a normal abrasive, even if the grinding depth is small, the grinding surface will be burned […]
