Ceramic Repair Putty
This diffuser would receive extreme cavitation wear from processing high velocity water. The wear was so sever, that the leading edges of the blades were completely worn away. Previous method of repair was to replacing missing metal by welding. Welding would often cause heat distortion problems.
Complete repair areas were sandblasted to a SSPC-SP5 white metal finish. Surface areas were then chemically cleaned using Cleaner Blend 300. Ceramic Repair Putty was applied to replace missing metal and fill cavitated areas deeper than 1/8". Following a partial cure of Ceramic Repair Putty, (4 hours), Brushable Ceramic was applied to a thickness of 30 mils in two coats at 15 mils each. Brushable Ceramic provides a long lasting, low co-efficient to friction protective surface coating with outstanding abrasion resistance in a slurry application.
