series is measured in seconds to illustrate the initial rate based on the catalytic effect. These data show that the lowest TCP concentration result in the highest percent of the TCP molecules that are converted to deposit. The deposit rate for 0.016 mol percent TCP at 700°C is about 4 molecular layers per second.

Our ability to run wear tests with vapor-delivered lubricant on a continuous basis is limited to 375°C in a four-ball wear tester. Wear test data at 10 kilograms load as a function of mol percent TCP in nitrogen is shown in Figure 8. These data show effective lubrication of the TCP vapor from 0.1 to 1.0 mol percent TCP vapor in nitrogen. The
