...Abstract Abstract In the course of a general overhaul, the crankpins and main journals (3 in. diam) of the crankshaft of a four-cylinder oil engine were built up by metal spraying. Four weeks later, the shaft broke through the pin remote from the flywheel (driving) end. The fracture...

... a year prior to failure the inner race of the roller bearing became slack on the shaft and the seating was built up by the metal-spray process. The shaft was machined to form a rough thread to provide the requisite mechanical key for the sprayed-on metal. Part of this sprayed-on layer became detached...

An alternative method of reclamation, and in many cases a preferable one, employs the technique of metal spraying and although a sprayed metal layer contributes little to the static strength of a built-up shaft, it does not result in severe deterioration in fatigue properties as does the method...

.... The reason why the rod had been built up in this manner was not clear, since a coating of steel on steel would not be expected to confer superior corrosion resistance although it might improve the resistance to wear. Inquiry revealed that the rods had suffered corrosive attack, presumably insufficiently...
