摘要：
The paper examines and compares the properties of Al2O3 coatings sprayed using two methods: arc plasma spraying (APS) of micron powders (average particle size is 45 μm) and suspension plasma spraying (SPS) (average particle size is 2.9 μm). A system for feeding suspension into plasma spray is developed and fabricated. It is established that SPS coatings contain finer structural components than APS. This improves their mechanical characteristics such as microhardness and indentation fracture toughness.
