Abstract : An investigation of the surface migration of thin films of Apiezon C on metal substrates was undertaken. The study was initiated in order to determine the effect of temperature gradients on the distribution of lubricants in spacecraft mechanical assemblies. It was discovered that temperature gradients of 0.5C/cm led to almost complete oil-film migration toward the colder end after three days. A larger gradient of 2.0C/cm led to an approximately equivalent transfer after one day.
