Experiments conducted to reduce losses caused by friction in diesel and spark-ignition engines confirmed the problem of friction and demonstrated that this environment was difficult for any lubricant to endure. Matrix coatings, however, had proved their worth in other hot-engine applications.
Xylan 1010 was applied to pistons which were then operated for a quarter of a million miles. The coating showed some signs of scorching — indicating that the pistons ran in excess of 260°C/500°F — but it was still operational, and the pistons showed little wear.
Xylan keeps functioning even
at elevated temperatures.
