Measure their microhardness, abrasion resistance, erosion resistance under conditions of cavitation in 3% aqueous solution of sodium chloride and corrosion resistance in this medium at 25 ° C and a pressure of 0.1 MPa, as well as autoclave in distilled water at a temperature of 330 oC and pressure of 15 MPa. In forming the coating used mechanism tverdorastvorimogo hardening with increasing heat resistance. Found that coverage of the system Ti-Zr-TiN had higher values of erosion and corrosion resistance compared to steel and can be used to protect elements of the valves, which operate in the secondary circuit accident. For items that run at higher settings, in particular, steam temperature 560-580 ° C, a pressure greater than 20 MPa, it is advisable to use multi-layer coating system Ti-Ni-TiN. The estimates show that the coatings can provide increased service life of elements of the locking-regulating devices in 1,5-2 times. The study described in an article aimed at the magazine "Physical-chemical mechanics of materials".
