- a focusing gun or even a mixing chamber, which is formed (ie solid pieces or surface coatings) of a harder material, will be used.
- the abrasive particles used in particular harder than corundum, thus making it possible to overcome the problem of erosion caused by these abrasive particles, in particular corundum.
- the material of the focusing gun may be tungsten carbide containing a low level of cobalt ( ⁇ 0.5%), silicon carbide, boron, titanium or other, cubic boron nitride, diamond or any material compatible and harder than corundum.
- it is essential that at least the focusing gun of the jet is made of a material resistant to erosion caused by the abrasive particles because it is the gun that undergoes the stronger erosion.
- olivine can also be used, as shown by additional tests performed under the same conditions as the previous tests.
