Abstract
This paper aims to establish the influence of temperature and duration of immersion on the thickness of zinc layer deposited through a thermal process, in correlation with the chemical composition of melted zinc. Layers obtained in microalloyed zinc with nickel, bismuth, tin, lead, aluminium, at different times of immersion and temperature, are analyzed. In terms of layer thickness, melted zinc microalloyed with bismuth and / or lead to coating to increase the content in these elements has thicknesses of increasingly small effect given the increasing fluidity of the melt in their presence. Decreased thickness of the layer is enhanced by increasing temperature and decreasing the duration of immersion. Best results are obtained at a temperature of 460 0C and 5 seconds of immersion time.
