A method for processing a component is provided and includes masking a first portion of the component with a maskant. The maskant includes a slurry having a plurality of particles in a fluid carrier. The plurality of particles comprises at least one of silicon, carbon, one or more rare earth disilicates, monosilicates or oxides, and combinations thereof. The method includes depositing a silicon-based coating on a second portion of the component via a chemical vapor deposition process and removing the maskant and any overlying silicon-based coating from the first portion of the component.

A solid state heater and methods of manufacturing the heater is disclosed. The heater comprises a unitary component that includes portions that are graphite and other portions that are silicon carbide. Current is conducted through the graphite portion of the unitary structure between two or more terminals. The silicon carbide does not conduct electricity, but is effective at conducting the heat throughout the unitary component. In certain embodiments, chemical vapor conversion (CVC) is used to create the solid state heater. If desired, a coating may be applied to the unitary component to protect it from a harsh environment.

A method for manufacturing a pillar-shaped honeycomb fired body including: measuring a firing shrinkage at an end surface of a first pillar-shaped honeycomb firing body at every predetermined angle for one round based on a portion that has been located at the center of a die when a green body passes through the die, obtaining a second pillar-shaped honeycomb formed body having a corrected end surface contour by modifying an annular mask used for extrusion molding based on a result of the measuring, and then obtaining a second pillar-shaped honeycomb fired body by performing drying and firing.

The method of curing reinforced concrete uses a liquid membrane-forming curing compound for the curing of reinforced concrete, but without fully coating the reinforced concrete with the curing compound, thus allowing for oxygen permeation through the reinforced concrete to effect passive layer formation on steel rebar embedded in the reinforced concrete. Prior to curing, a mask is applied to at least one surface of a slab of reinforced concrete, such that the mask covers about 10% of the surface area of the at least one surface. The at least one surface of the slab of reinforced concrete is then coated with a liquid membrane-forming curing compound. The liquid membrane-forming curing compound is allowed to dry, thus forming a curing compound layer on the at least one surface of the slab of reinforced concrete. The mask is then removed to form at least one uncoated region.
