BUILDING UP WORN PARTS.
In view of the recent research work which has shown corrosion to be an important factor in cylinder troubles, experiments have been made in England .in the application of a clever buildingup process to cylinder bores, pistons and valve seatings. In the first case, the bore is machined to a slightly greater diameter over the upper part, is provided with a nickel coating and is then finally ground and honed to the re-
quired size. Consequently, the surface exposed to the fiame and to the acidic products of combustion is of an anticorrosive nature. Pistons can be entirely covered with nickel by the same process or, alternatively, the coating can bfe applied simply to the ring grooves, in which wear is usually localised. Prolonged experiments are now being made to show the effect Of nickel deposited in this way upon cylinder troubles in general, and already, in the case of valve seatings. some excellent results have been obtained.
