| Abstract: | Porous ceramic coatings composed of Al2TiO5,anatase TiO2 and rutile TiO2 were prepared on the surface of TC4 alloy by micro-arc oxidation.The galvanic corrosion behavior of TC4 alloy and its micro-arc oxidation coating coupled with 45 steel,LY12 aluminum alloy and red copper was investigated.It was found that when coupled with TC4 alloy,45 steel and LY12 experienced serious galvanic corrosion and uneven pitting respectively,but red copper did not show obvious corrosion.Couple current for 45 steel,LYl2 alumi... |
