Abstract: 1,228,853. Coating metal. DAIKIN KOGYO CO. Ltd. and TOHO KASEI CO. Ltd. 7 May, 1968, No. 21643/68. Heading B2E. A method of coating a metal surface with a fluorine-containing polymer comprises forming a first glossy, chromium plating layer by an electrolytical method on the metal surface, etching the surface of this plating layer electrolytically by reversing the polarities of the electrodes, thus forming a number of pits, cracks or crevices therein, applying a dispersion of a fluorine-containing polymer to the etched surface and then sintering the polymer to form a continuous film of the polymer on the etched surface, thereby anchoring the film to the etched surface with the polymer filling the pits, cracks or crevices. Prior to forming the plating layer, the metal surface may be roughened mechanically or chemically. In a modification, a second chromium plating layer is superimposed on top of the first such layer using a plating bath temperature lower than that used in forming the first plating layer, the surface of the second layer being etched electrolytically by reversing the electrodes, after which the fluorine-containing polymer is applied. In another modification, either both of the plating layers when two are present or the one such plating layer is formed using an electric density higher than the optimum for forming a glossy chromium layer, so that projections are formed on the surface of the plating layer. In an example, the current density is increased from 20 A/dm<SP>2</SP> to 40 A/dm<SP>2</SP>. The fluorine-containing polymer may be polytetrafluorethylene, polychlorotrifluoroethylene or tetrafluoroethylene-hexafluoropropylene copolymer and the dispersion of such a polymer, may be applied to the metal substrate by spraying. The metal may be mild steel, copper, gun metal, aluminium or aluminium alloys.

A method of machining the convex surface of a blade 11, e.g. a turbine blade comprises reciprocating a cutter 20 along the length of the blade at a relatively high speed while simultaneously moving the cutter around the contour of the blade. In a machine for carrying out the method a head H carrying a spindle 50 and cutter 20 is reciprocated at variable speed, in order to maintain a constant cutting load throughout each stroke, by means of an hydraulic cylinder unit 60-63. Simultaneously the column C of the machine which carries the head H, and a saddle S are moved in a plane transverse to the axis of the blade under control of an electrical or hydraulic copying unit having a tracer 80 in contact with a template T. The rate of transverse movement is varied in dependence upon the radius of the blade contour in order to maintain a constant cutting load on the cutter 20.
