Many machine components must operate under conditions

that limit the effectiveness of oils and greases.

Such conditions include loads that are so high and/or speeds

that are so slow that a hydro-dynamic lubricating film cannot

be maintained (ftequently the case with plain bearings and

sliding surfaces). In addition adverse environmental condi-

tions may severely reduce the operating life and performancecapabilities of a lubricant to the extent that the machine

component may not function as required.

~~;~llt!Ib.J

--.JUp to now lubricating pastes containing metal powders

such as copper, nickel or aluminium have been used in

such cases. Although adding these metal powders enhanced

the load carrying capacity and temperature resistance it is

now recognized that they cause new problems - partly also

relating to health and safety risks.

With copper pastes:

As soon as the carrier oil has evaporated the remainingmetal powder gets into immediate contact with the surfaces

of the component being lubricated, and - owing to the

different voltage potentials of the metals in question -

contact corrosion can occur. Furthermore, copper dust

resulting ftom dry ftiction and wear can contaminate the

environment and drinking water.

With nickel pastes:

At above 200°C the carrier oils of the pastes evaporate

and what remains is pure metal powder which acts as a

separating agent. Nickel powder, however, is known to bea carcinogenic heavy metal and as such poses severe risksto human health.

With aluminium pastes:

Although aluminium powder - the key ingredient of such

pastes - is non-poisonous, but itcan react at high ftiction

temperatures so violently with the oxygen in the air that aso-called flash fire can occur.
