Title:
METHOD FOR HARDENING SURFACE OF PLATINUM MOLDED ARTICLE AND PLATINUM MOLDED ARTICLE HAVING HARDENED SURFACE
Document Type and Number:
WIPO Patent Application WO/2012/002176
Kind Code:
A1
Abstract:
Provided is a platinum molded article having a hardened surface, which has excellent self-weight deformation resistance even if the platinum molded article is thin, hardly deforms and is easy handle, has corrosion resistance and durability under high temperatures and pressure, and can prevent platinum particle growth and particle boundary corrosion in a reducing atmosphere, and also provided is a method for hardening the surface of a platinum molded article. The method for hardening the surface of a platinum molded article comprises: an application step for forming an application layer by applying an application solution containing an iridium salt and/or ruthenium salt to the surface of a platinum molded article (20); and a pyrolysis step for pyrolysis of the application layer in a nitrogen gas atmosphere or in a flame in order to convert the application layer to a coating layer (30) comprising iridium, ruthenium, or an alloy containing iridium and/or ruthenium.
