摘要： A method and apparatus for testing a ceramic member applies mechanical stress to the member by application of mechanical force and simultaneously applies thermal stress by creating a temperature gradient in the member by localized heating of a portion thereof. The mechanical stress is impact stress or may be applied by application of a static load to the ceramic member. The method is especially applied to the proof-testing a plurality of ceramic members for quality assurance, particularly engine valve members.
