Metal powder for wear-resistant coatings
RotoTec DuroTec 19910
Metal powder based on a self-flowing NiCrBSi alloy. Tough matrix with finely dispersed hard materials. High resistance to adhesion. Good resistance to metallic sliding friction, lubricated and unlubricated. Good emergency running properties. Resistant to corrosion and scaling. Can be machined. Spray coatings are heterogeneous and microporous.
Technical data
DIN EN 1274: ~ 2.10 - 125/38 - coated
Hardness [HV 10]: 340*
Grain size distribution [μm]: 38 - 125
Density [g/cm3]: 7.5
Applications
For flame spraying without melting of unalloyed, low-alloy and high-alloy steels and the corresponding cast steel grades.
Typical applications are
Slideways, pistons, bearing journals of shafts and axles, packing running surfaces in stuffing boxes and sliding surfaces in tools, piston rods.
Processing instructions
Remove damaged material. Round off or chamfer edges. Clean spray areas, preheat to 50 - 150 °C and roughen. Spray on a layer of primer powder in the preheated state. Maintain spray coat temperature between 50 °C and 200 °C and apply up to the desired coat thickness. Do not exceed a layer thickness of 2 mm. Allow to cool in still air.
Spray gun: CastoDyn DS 8000
Primer powder: ProXon 21021
*The achievable hardness values depend on the selected spraying parameters, preheating temperatures, etc. No guarantee can therefore be given that the hardness values will be achieved.
