ABSTRACT:
A surface processing method by blowing submicron particles is disclosed, in which submicron particles are blown against a surface of a work to deposit a layer of the material of the particles on a surface of the work, or etching the surface of the work.
The processing method uses blowing air stream containing submicron particles having average particles size ranging between 0.01 and 3.0 .mu.m. The deposition or etching is effected depending on an incident angle of the particles to the surface of work. According to the method deposition of the material can be effected with very high deposition rate and in case of etching very smooth etched surface is obtained.
