Abstract
A coating of at least one carbide of one or more of Ti, Zr, V, Cb, Ta, Mo and Cr is produced on a ferrous metal mass by applying successive layers of "asymmetric particles" of one or more of the said carbides with or without binder metal(s), and each time a layer is applied heating under non-oxidising conditions both the layer and the underlying surface to which the layer is applied, sufficiently to effect welding of the layer to the underlying surface but insufficient, at least in the case of the last layer(s), to alter materially the asymmetric nature of the carbide particles. "Asymmetric particles" are irregularly shaped incomplete crystals such as obtained by ball-milling. The layers may be applied as pre-formed laminae, or as powder; heating may be by a gas welding torch or a shrouded arc using carton or tungsten electrodes. The coating, while still plastic, may be shaped by pressure between metal or carbon formers. In an Example, 85 per cent re-crystallized carbides (87 1/2 parts Ti C, 11 parts Cb C, 1 1/2 parts Ta C) and 15 per cent Ni-Cr binder alloy of particle size 3m and less, the carbides being asymmetric, was mixed with 1 per cent of organic binder (20 per cent camphor in acetone) and mortared. It was then compressed at about 1/2 ton p.s.i. while vibrated in a mould, then presintered at 1200 DEG C. It was then cast to size, placed on a base of 0.5 per cent carbon steel which was partially immersed in water, and an arc struck with a tungsten electrode shrouded in nitrogen to weld the layer to the base. This was repeated with two other similar compacted layers and finally with two containing no binder metal. The hardness of successive layers increased. In a second Example the powder of the first Example was projected through a nitrogen-shrouded arc struck between a tungsten electrode and the upper face of a 0.5 per cent carbon steel base cooled as before. Successive layers were added each about 1/16 in. thick, the last two being free from binder metal powder. Shaping of each of the above produced layers whilst plastic by means of a steel former using 20 tons p.s.i. maintained the hardness but gave increased shock resistance.
