Deposit Forming Tendencies of Aircraft Turbine Lubricants

This test method describes  a procedure for  determining the  deposit  and  sludge  forming  tendencies  of  aircraft gas  turbine  lubricants when  a sample  of the  oil is circulated  under  controlled conditions...

Corrosion fog cabinet

A number of test  methods, of which  this is one, make  use  of  bench  tests to  indicate  how  well  a lubricant will  protect steel  from rusting. These  methods  are  most  often  used  for  comparatively  low...

Chlorine in lubricating oils

In the first  methods the  sample  is oxidized  by  combustion  in a  bomb  containing  oxygen  under  pressure. The  chlorine  compounds thus  liberated  are  absorbed  in a  sodium carbonate  solution...

Chemical Analysis for Metals in Lubricating oils

These methods of chemical analysis are intended  for the  determination of barium, tin, silica, zinc, aluminum, calcium, magnesium, sodium and potassium in  new  and used  lubricating  oils. Other metallic elements, sulfur, phosphorus and  chlorine in  amounts ...

Sulfur in Gear Oils

In this method  the sample is vaporized  and  burned in a  stream of air, and  the  oxidation completed  by passing  over  quartz particles  maintained  at a temperature  of 950 to 1000 degree C. The combustion  products are then ...

Pentane and Benzene Insolubles in Used Lubricating Oils

Normals  pentane insolubles are the  insoluble  matter  which can be separated from a solution of oil  in n-pentane and  in addition  to benzene  insolubles, may  include  insoluble resinous  bitumens produced from the  oxidation of oil....

Aniline Point of Petroleum Products

Aniline point is the minimum equilibrium  solution temperature, generally given  in F although C is also used, for  equal  volumes  of  aniline  and  oil. Aromatic  compounds in oils  contribute to a low  aniline point  which  in ...

Missile and Space Vehicles Gear Mechanisms and their Lubrication

While details of space vehicles are not publicized, it can be expected that gears may enter, even if only for small instruments. These will no doubt be of a nature which will not require fluid lubrication. However, Hartman^24 mentions that there may be a gear drive between the turbine and the shaft...
