Abstract

A method of making workpieces of non-circular cross-section, such as gears, comprises the steps of bright annealing a steel bar, treating with muriatic acid and hot phosphate solution, cooling, oiling, cold-drawing through a shaped die with powdered graphite lubrication, straightening, cutting into lengths and finish-machining. The phosphating treatment comprises immersion for 4-8 minutes in a bath comprising 2.6% Phosphatin 10A, 8.4% Phosphatin 10E, remainder water. The temperature of the bath is 90-100 DEG C. The compositions of Phosphatin 10A and 10E are given as follows. <TABS:0974188/C6-C7/1>
