PROBLEM TO BE SOLVED: To provide a new inorganic coating film which contains the group 4A element, oxygen and boron, and to provide a method of producing an inorganic coating film by which a dense film is easily formed. SOLUTION: The inorganic coating film is formed on a substrate. The film consists of one layer or plural layers, and each layer contains the group 4A element, oxygen, and boron. Preferably, the group 4A element is titanium or zirconium, and the base material consists of metal, ceramics, or plastics. In the method of producing the inorganic coating film, a current is made to flow through a sample containing the group 4A element and oxygen, and the sample is explosively thermal-sprayed to form a film of one layer or plural layers on the base material. |
