A blast treatment method for blasting an object includes: a step in which an explosive is detonated inside a pressure vessel () which has an elasto-plastic metal, thereby imparting to the pressure vessel () an initial load wherein the primary and secondary stress generated in at least a portion of the pressure vessel becomes high enough to be in a plastic region exceeding the elastic region, thereby generating a shakedown state in the pressure vessel (); and a subsequent step in which a treatment explosive () is detonated within the pressure vessel (), thereby blasting the object ().

Method for blasting object to be treated in pressure vessel

An aspect of the present invention is a method of processing a waste material that contains mercury or a mercury compound, and chlorine or a mercury chloride, the method including a step of adding a chlorine scavenger to the waste material, and stowing the waste material in a treatment vessel; and a step of subjecting the waste material to a blasting treatment by fitting an explosive to the treatment vessel and detonating the explosive inside a pressure-proof container.

Method of processing waste material

Aluminum alloy comprising an anodic oxidation coating and a ceramic coating formed on a surface of the anodic oxidation coating, wherein the anodic oxidation coating contains one or more elements selected from the group consisting of C, N, P, F, B and S at a content of each element in an amount of 0.1 mass % or more, and wherein the ceramic coating comprises one or more selected from the group consisting of oxide, nitride, carbonitride, boride and silicide, wherein when the anodic oxidation coating contains S only, the surface of the aluminum alloy or of the anodic oxidation coating has an average roughness Ra of 0.3 &mgr;m or more.
