Abstract (en)

A method of treating a surface of a metal plate (10) comprises projecting sharp non-metallic particles at the surface whilst the surface is at a temperature such as to be in a fluid or substantially fluid state. The particles employed are preferably made by forming a mix of particles of granite, feldspathic rock and aluminium oxide with a kaolin or other clay binder, compressing the mix into blocks, firing and crushing the blocks. The blocks may be crushed before or after firing.
