The ceramiccomprises alumina, and is made macroporous by spraying a mixture of alumina sol and alumina particles with no more than 35 % by weight of dispersible alumina.

The plasma spraying experiments were carried out using various argon-nitrogen volume mixture ratios, and the corresponding coatings were obtained.
