scope:

NPR-ISO/TR 14232-2 gives guidelines for selecting the powder chemistry or composition for obtaining an objective coating performance. It provides comparisons of coating performance for wear resistance (Table 1) and corrosion resistance (Table 2) to spray powder chemistry/composition. The wear types shown in Table 1 are abrasive, adhesive, chemical, erosion, fretting, impact, rolling and sliding. The corrosion types shown in Table 2 are acid/alkaline/salt, atmospheric, biochemical, biological, chemical agent, chemicals in food, combustion gas, sea water, fresh water, molten metal, molten salt, non-aqueous solution, soil, steam and miscellaneous. The tables give the coating chemistries and describe the composition of spray powder of metals/alloys, ceramics and cermets. The guidelines have been produced on the basis of academic literature, in particular the Journal of Thermal Spray Technology and the Proceedings of the International Thermal Spray Conference.
