Abstract
The invention relates to a process for the high-temperature galvanization of steel parts containing from 0.01 to 0.6 percent by weight of silicon at temperatures of 470.degree. to 550.degree. C., the steel parts being immersed in a zinc melt containing lead in a quantity up to that maximally soluble at the operational temperature employed but containing at least about 2 percent by weight based upon the weight of the zinc melt. In this manner thick and uniform coatings of zinc are achieved.
Claims2
In the process for high-temperature galvanizing steel parts containing from 0.01 to 0.6 percent by weight of silicon by immersion into molten zinc heated to about 470.degree. to 550.degree. C.,
- the improvement which comprises using a zinc melt containing lead in a quantity up to the maximally soluble amount at the operational temperature employed but at least about 2 percent by weight based upon the weight of the zinc melt.
