For more than a quarter of a century the technique of metal spraying has been a commercial success in this country, but it is only in the past few years that its possibilities as an aid to lubrication have been fully recognised. Exhaustive tests have shown that metalsprayed journals, for example, have an increased life of at least 40 per cent, due to the capacity of the sprayed metal for retaining an oil film. While the metal spraying method of building up worn parts cannot be applied universally to all worn lubricated surfaces for instance, it is unsuitable for certain components which are subject to appreciable shock, such as cams, gear teeth, etc.,it offers an efficient means of salvaging much material that would normally be discarded, and simultaneously increases the efficiency of the built up part, when this has to be lubricated.

There are still a great many people, unfortunately a number of them are engineers, who regard lubrication merely as oil, a necessary evil that must be dispensed by the greaser with his oil can or by the car owner who has heard it said that his engine will not run without it. Fortunately, most engineers and many other people, are becoming more lubrication minded and are realising that correct lubrication is a science and when correctly applied can save them a lot of money by reducing breakdowns and thus increasing production.

In the first part of this article, in our last issue, DR. BRANCKER discussed the fundamental elements of emulsification, the orientation and wetting theories and their connections with lubrication. In this part he discusses metal cleaning, solid emulsions and atomisation. The theories discussed are of primary importance in connection with spraying metal surfaces for corrosion inhibition or for lubrication. The theories of atomisation are also important in connection with lubrication by aerosols.
High temperature lubrication1949 Industrial Lubrication and Tribology

The lubrication of equipment operating under very high temperatures has for many years presented a serious problem to industry. Considerable thought has been given to the design of rubbing parts to enable them to function with efficient lubrication and sometimes without any lubricant. This has been made necessary, in the past, by the fact that there has been no lubricant suitable for temperatures beyond the range of oils and greases. There are various fillers which offer heat resistance, but they do not provide efficient lubrication, they may enable equipment to work but only at the cost of wear. The manufacturer has turned his attention to heat resisting hardened steels which will resist spalling and undue wear, but cost often militates against the widespread use of such materials.
The use of CALCIUM STEARATE in wire drawing1949 Industrial Lubrication and Tribology

The tremendous shearing forces incurred when wire is cold drawn through one or a series of dies, have always presented a difficult problem in lubrication. In view of the increased rate of production involving faster travel of the wire through the die, the lubrication and cooling of the wire and die become more difficult of satisfactory solution. It is usual to employ soaps of the alkaline earth metals for this work and of these, calcium stearate is very widely used.
