What will eventually result from oxidation of the spraying coating?

-------------------------------------------------------

answers:
Kathy say: Material oxidation and WC decomposition will often occur during the deposition of the coating. the oxidation results in coating embrittlement and subsequent reduction of its service lifetime in conditions of abrasive wear, erosion, and especially cavitation. and the embrittlement of WC-coatings is directly related to a high combustion temperature, usually more than 3000 degrees as well as the presence of oxygen in the combustion products.
