Title:
METHOD FOR EVALUATION TESTING OF MATERIAL FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2013/114777
Kind Code:
A1
Abstract:
An oxide film is formed on the surface of a sample configured from a metallic material by maintaining the sample in an oxygen-containing atmosphere at a temperature of 800ºC-1100ºC, and the sample provided with the oxide film is immersed for a certain period of time in a corrosive solution including acid and NaCl. After immersion, the corrosion state (density, cracking, and so forth of the oxide film) of the sample is evaluated. The corrosion resistance properties of the sample are able to be evaluated conveniently, appropriately, and in a short period of time, by causing accelerated corrosion in an environment simulating the actual environment of an internal combustion engine.
