on ZK60 and ME20 alloys was investigated. The results indicated that differences in the alloy compositions significantly influenced the initial deposition process and the adhesive strength, corrosion... activation rather than on the precipitates. Owing to differences in the initial deposition process, the coating on ZK60 alloy had higher adhesive strength and better corrosion resistance than that on ME20......
, the medium elastic module value is more suitable for stress distribution in crown-luting cement-substrate interfaces. Key words: finite element modeling; stress analysis; adhesive and luting cement... the patients, including other engineering and dentistry materials. It is well-known that the useful layer life depends on either detachment of the coating, adhesive failure, or fracture of the layer......
