H ow ever, it is subject to some bottleneck issues, such as high tritium permeability, corrosion to structural material by liquid LiPb and MHD ( Magnetohydro- dynamics) effects caused by flowing LiPb, etc. . Coatings on the surface of blanket structural materials is one of the key technologies to solve the above problems. T his 2 3 study is aimed at preparing multifunctional Al O coatings on the China Low Activation Martensitic ( CLAM) steel w ith air plasma spraying ( APS) process. T he results of the experiment show that the mean adhesion strength of coating is 311 M
