Influence of number of fusions on mechanical properties of Ducinox alloy
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 78, Issue 1
Abstract
Purpose: The purpose of the test was to specify influence of re-fusions of the nickelchromiumprosthetic alloy Ducinox on its strength properties.Design/methodology/approach: The tests were carried out on the samples cast of theDucinox alloy molten once, twice and three times. The hardness has been measured usingthe Vickers method; the tensile strength has been also specified. The samples designed forstrength tests were subjected to X-ray control to find possible defects that would eliminatethe samples from further tests. The last test was observation of fractures occurred as a resultof the strength tests, under the microscope.Findings: Both hardness measurements and strength tests did not show statisticallysignificant differences among individual groups of samples.Practical implications: Based on the results of the tests carried out, it can be found thatre-fusion of the alloy Ducinox has no influence on its tensile strength. Thereby, in the dentaltechnology practice, it is possible to add the casting scrap to pure metallic alloy withoutinfluence on strength of prosthetic element castings.Originality/value: This is an well-known method of analysis which is applied in manyscientific fields. However in modern prosthetics it is new approach.
