Thermal spray coating, member for semiconductor manufacturing equipment, feedstock material for thermal spray, and method for producing thermal spray coating
A thermal spray coating according to the present invention contains mainly magnesium, aluminum, oxygen, and nitrogen and has, as a main phase, a crystal phase of a MgO—AlN solid solution in which aluminum nitride is dissolved with magnesium oxide. The thermal spray coating is obtained by thermal spray of powder of a ceramic material containing mainly magnesium, aluminum, oxygen, and nitrogen and having, as a main phase, a crystal phase of a MgO—AlN solid solution in which aluminum nitride is dissolved with magnesium oxide.
