A METHOD OF ADHERING MOLYBDENUM DISULFIDE TO A METAL SURFACE WHICH COMPRISES COATING THE METAL SURFACE WITH A THIN LAYER OF A COMPOSITION COMPRISING FINE PARTICLE MOLYBDNUM DISULFIDE IN DISPERSION IN AN AQUEOUS AMMONIACAL THIXOTROPIC SUSPESOID OF RANDOMLY ORIENTED COLLOIDAL BOEHMITE ALUMINA FIBRILS IN WHICH SAID ALUMINA FIBRILS ARE PRESENT IN THE PROPORTION OF FROM ABOUT 4 TO 16.5% BY WEIGHT BASED ON THE WEIGHT OF SAID MOLYBDNUM DISULFIDE. AND DEHYDRATING SAID THIN LAYER OF THE COMPOSITION ON THE METAL SURFACE BY BAKING IT IN AIR AT A TEMPERATURE OF FROM ABOUT 450 TO 550*F. AND THE COMBINED TOTAL OF SAID ALUMINA FIBRILS AND SAID MOLYHBDENUM DISULFIDE IS FROM ABOUT 5 TO 60% BY WEIGHT OF THE COMPOSITION.
