Effects of electrolytic jet plasma oxidation (EJPO) coatings on thermal behavior of engine cylinders

Aluminum engine blocks with ceramic-coated cylinder bores can effectively reduce the self-weight and largely improve the wear resistance. However, the presence of coatings to some extent also affects the heat transfer of internal combustion (IC) engine between the cylinder and the coolant due to their low thermal conductivities. In this paper, electrolytic jet plasma oxidation (EJPO) coatings were adopted to deposit on the engine cylinder …
