Abstract: A process of forming a visible textural surface on a decorative acoustical panel having a fibrous body portion is disclosed herein. This process includes coating an exterior surface of the body with a film of hardening liquid, distributing individual granules of particulate material generally uniformly over a substantial portion of the exterior surface to provide a granular texture to the surface, and coating the granules with a film of hardening liquid, which film is insufficient to eliminate the granular texture but which adheres the granules to the exterior surface. Thereafter a part of the surface on which the liquid coated granules are located is indented. These indentations extend from the exterior surface and penetrate partway into the panel body to cause the displacement of part of the surface, thereby forming wall portions. These wall portions include some of the granules.

Abstract: Low temperature aluminum diffusion is more uniform when effected with a pack energized by aluminum chloride or other material that does not generate nitrogen, and gives food protection against marine corrosion of steels, and particularly when there is a chromate-type coating applied over the aluminizing. Highly effective chromate-type coating mixture consists essentially of aqueous solution of chromic and phosphoric acid also containing magnesium salts of said acids and dispersed polytetrafluoroethylene particles. Such coating mixture is best applied over porous pre-coating of colloidal inert particles. Aluminized superalloy can be heated in air to whiten it, then cleaned to give product having more ductile case. Such coated superalloy can also be stripped of coating by aqueous HNO.sub.3 --HF--CrO.sub.3 bath.

Thusly applied, it has been found that well defined colored marks are formed on the surface of the paper base on marking the surface with a colorless marking ink.

Abstract: Fused silicide coatings for protecting niobium alloy substrates are modified by providing dispersed nucleation sites in the form of discrete particles in the coating. The discrete particles have a thermal expansion coefficient lower than that of the fused silicide material. This alters the microstructure and reduces the thermal expansion coefficient of the coating so as to minimize the number of tensile cracks.
