abrasive machining processes - IIT Kanpur
SiC abrasives are harder than friable Al 2 O 3 but they are usually inferior for grinding most ferrous materials. This is due to the dissociation of SiC to react with and adhere to iron at elevated temperatures. (Affinity of silicon or carbon for the workpiece ) Therefore, SiC tends to work better than Al 2 O 3 on some ferrous metals with ...
