The Influence on Castability of Nickel-chromium alloys According to Burn-out Temperature and Recast Content Ratio
ÚÓüøܼ
Abstract
The castability of base metal alloys for dental casting is influenced by burn-out temperature and recast percentage.
Burn-out temperatures for casting are set at 200¢µ interval from 1000¢µ to 1800¢µ.
According to recast metal percent in new cast alloy, metal alloys are tested.
The results are as follows:
1. In the new alloy (100%), the castability is the most.
2. In the burn-out temperature in 1600-1800¢µ, castability of 100% new alloy was more four times than of 50% new alloy plus 50% recast alloy.
The using of 50% new alloy and 50% recast alloy, therefore, was unlike in cast ability.
3. The burn-out temperature in 1600¢µ, castability of 100% new alloy was more than four times in soaking 20 minutes, but there was no any difference at 1800¢µ.
4. It is investigated that the optimal burn-out temperature is 1600¢µ for the C & B alloy.
