Abstract

Powder detachment from coatings during press forming of Zn-Ni precoated steel sheets increases die wear and maintenance costs. Experimental design helped to establish that powder detachment rises by increasing coating thickness or bath temperature. Otherwise, the use of high flow rates and the presence of an intermediate layer of nickel help to reduce powdering. Temperature and flow rate affect the alloy composition. In the range 10 to 15 % Ni, powdering increases as the alloy becomes richer in nickel. This behaviour is attributed to changes in structure and ductility of the alloy.
