A method for producing a coating system includes depositing a first slurry on a composite substrate, the first slurry including a first carrier fluid and boron-containing powder, removing the first carrier fluid and consolidating the boron-containing powder to form a boron-containing layer on the composite substrate, depositing a silicon-containing coating on the boron-containing layer and consolidating the silicon-containing coating to form a silicon-containing layer, and depositing at least one layer of phosphate on the silicon-containing layer.

A method of manufacturing a ceramic matrix composite component may include introducing a gaseous precursor into an inlet portion of a chamber that houses a porous preform and introducing a gaseous mitigation agent into an outlet portion of the chamber that is downstream of the inlet portion of the chamber. The gaseous precursor may include methyltrichlorosilane (MTS) and the gaseous mitigation agent may include hydrogen gas. The introduction of the gaseous precursor may result in densification of the porous preform(s) and the introduction of the gaseous mitigation agent may shift the reaction equilibrium to disfavor the formation of harmful and/or pyrophoric byproduct deposits, which can accumulate in an exhaust conduit 340 of the system.

The present invention provides a process for producing a friction material for a construction waste filler, including steps of: (S1) sorting a building material, removing fiber impurities, calcining, removing white garbage and metal impurities, and obtaining a first intermediate product; (S2) sifting and removing dust from the first intermediate product, obtaining an intermediate filler, cooling and then soaking after performing calcination on the intermediate filler, dehydrating, drying and obtaining a material to be mixed; (S3) evenly mixing the material to be mixed, graphite, molybdenum disulfide and other media materials, performing enhancement treatment, grinding and obtaining a building filler; and (S4) mixing composite fiber, phenolic resin, the building filler, friction material, pyrite, carbon black, alumina, and brass powder, stirring in a mixer for 20-40 min till all materials are fused, taking out a fused mixture, barreling, and obtaining the friction material for the construction waste filler.

A dry polymer modified cement to receive topical aggregate to form a high friction surface on trafficked pavement substrates (asphalt, concrete). The dry polymer modified cement is a thin overlay that handles the load of traffic in a relatively short time and has a relatively long life cycle. Prior to curing, the dry polymer modified cement also acts as an adhesive layer to receive and hold aggregate that is applied thereto. The dry polymer modified cement is prepared by mixing a cement mix with water where the cement mix includes cement (ordinary Portland cement), dry polymers and aggregate. The aggregate may have gradations that meet the ASTM C144 specification or may have finer gradations to allow for easier penetration of the topical aggregate by the dry polymer modified cement. The high friction surface may be patterned to provide improved performance.
