Hard facing of various components in the aircraft gas-turbine engine and in industrial apphcations for textile machinery parts, oil and gas machinery parts, paper-shtting knives, etc, is estimated at 1 x 10 in 1995 with an estimated growth rate of 5% annually. The mix is approximately 45% aerospace apphcations, 55% industrial apphcations. Additionally, repair coatings for gas-turbine blades and vanes is estimated at 500 x 10 . These coatings are primarily deposited by plasma spray, arc-wire, HVOF, and detonation gun techniques. 

Lubricity of crystalline polymers is usually higher than that of amorphous polymers. Excellent machinery parts are made from crystalline nylon-6,6 resins, eg, gears, cams, wedges, and other components not requiring lubrication. Gears made of amorphous polyimide resin, on the other hand, do not exhibit this feature.

The term lubricant is not used in a standard way. Synthetic lubricants in automotion and in machinery in general - mainly liquids - are designed to reduce the friction and wear of/or between (mainly) metallic parts in the widest sense. In a similar way, lubricants are understood in textile and fibre processing, where they are externally applied to reduce friction between textile fibres and metallic machinery parts. The same applies for example, to processing of PVC films on a calendar, where lubricants may be fed externally by a roller device. 

Internal lubricants are added as part of the formulation during plastics processing. Depending on their compatibility with the resin they can have a more pronounced internal lubrication effect mainly interacting with the molecules of the polymer melt or they can have a more pronounced external effect, i.e. additionally reduce friction at the interface between processed plastic melt and metallic machinery parts [121, 151-153]. Lubricants in resin systems improve flow characteristics and reduce adhesion in the polymer melt. Added in very small quantities... 

Some metals such as copper can act as oxidation catalysts and their presence increases the rate of oxidative degradation of the lubricant. Other metals such as zinc can be corrosive to silver machinery parts such as bearings and bushings. Determining the oil s metallic concentration, the accumulation rate and the sources of the individual metals is an important part of oil analysis.

Machinery parts, performing rotational motion only, such as propellers, have rotational symmetry only. An example is the four-blade propeller in Figure 2-19c. 

Structural stresses are stresses produced in structural members because of the weights they support. The weights provide the loadings. These stresses are found in building foundations and frameworks, as well as in machinery parts. 

Abrasion is the dominant wear mechanism, if the material to be extruded or its components are harder than the surrounding housing walls or machinery parts. 

Can we predict whether a certain metal will be oxidized either by an acid or by a particular salt This question is of practical importance as well as chemical interest. According to Equation 4.27, for example, it would be unwise to store a solution of nickel nitrate in an iron container because the solution would dissolve the container. When a metal is oxidized, it forms various compounds. Extensive oxidation can lead to the failure of metal machinery parts or the deterioration of metal structures.
