PCT No. PCT/GB95/00143 Sec. 371 Date Nov. 15, 1996 Sec. 102(e) Date Nov. 15, 1996 PCT Filed Jan. 25, 1995 PCT Pub. No. WO95/20256 PCT Pub. Date Jul. 27, 1995A method of coating an area of an electrode with an erosion resistant material. The method comprises bringing into contact with the area a web which contains the erosion resistant material and which carries an adhesive so that the web adheres to the electrode. The electrode and the adhered web are then heated to a temperature high enough to cause the adhesive to decompose, volatilize, or both such that the adhesive is substantially eliminated from the web and such that the erosion resistant material fuses and bonds to the electrode.
