    摘要: A process for the production of a lanthanum chromite film, including the steps of preparing a plasma spray powder by mixing 1-15 parts by weight of powdery chromium oxide powder to 100 parts by weight of powdery lanthanum chromite, this lanthanum chromite having a composition ratio of A sites to B-sites being in a range of 1:1 to 1:0.9, forming a plasma sprayed film by plasma spraying the plasma spray powder onto a substrate, and forming the lanthanum chromite film by heat treating the resulting plasma sprayed film. The plasma spray powder may be produced by preparing a mixed powder by adding 1-15 parts by weight of powdery chromium oxide to 100 parts by weight of a synthesis powder capable of producing the lanthanum chromite film by heat treatment, the synthesis powder containing at least chromium oxide and lanthanum chromite and the lanthanum chromite film having a composition ratio of A-sites to B-sites being in a range of 1:1 to 1:0.9, obtaining a synthesized product by heating the mixed powder, and granulating the synthesized product.

    摘要: A base member made of a metal in which aluminum is included, ceramics in which an aluminum element is included, or a composition member constructed by a metal in which aluminum and ceramics are included, is provided in a container in which a solid fluorine compound such as NaHF2 is filled. Then, the container is heated at a temperature higher than a decomposition temperature of the solid fluorine compound. After that, the base member is subjected to a heat treatment with the decomposed gas of the solid fluorine compound to form a fluoride layer on a surface of the base member. In this manner, it is possible to obtain an anti-corrosion member which shows a high corrosion property with respect to the corrosion gas of halogen series and its plasma, particularly with respect to chlorine gas and its plasma.
