RotoTec FrixTec 19850 Metal powder

RotoTec FrixTec 19850

Metal powder based on a copper-aluminum alloy. High resistance to adhesion. Good resistance to metallic sliding friction, lubricated and unlubricated. Good emergency running properties. Withstands impact stress. Corrosion resistant to water (drinking, industrial and sea water), weathering, diluted acids (acetic and sulphuric acid) and alkalis except ammonia. Can be machined. Work-hardening.

Technical data
Hardness [HV 10]: 130*
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
Plain bearings, roller bearing seats of idlers, slider seats, pulleys, piston shells, slideways, turbine blades, bearing shells and clutch forks.

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 3 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.
