Abstract

A silicon carbide-calcium oxide stabilized zirconia composite thermal barrier coating and a preparation method of the present invention, comprising: step 1, configuring ZrOCl 2 ·8H 2 O / Ca(NO 3 ) 2 4H 2 O mixed solution A; Step 2, add excessive ammoniacal liquor dropwise to mixed solution A and continue to stir to generate white precipitate; Step 3, polycarbosilane is dissolved in p-xylene solution to obtain solution B; Step 4, solution B and The PVA aqueous solution is added to the mixed solution A to obtain the mixture; step 5, the mixture is ball-milled in a roller ball mill to obtain the slurry after ball milling; step 6, the ball-milled slurry is granulated on a spray granulator to remove moisture After getting dry Zr(OH) 4 , Ca(OH) 2 and the spherical mixed powder of polycarbosilane; step 7, the spherical mixed powder obtained after granulation is placed in a powder feeder, and thermally sprayed on the surface of the metal substrate by means of vacuum plasma spraying. (OH) 4 , Ca(OH) 2 and polycarbosilane are pyrolyzed to form a high-density and high-wear resistance, and a high-density SiC‑CSZ composite wear-resistant thermal barrier coating.

Description

Silicon carbide-calcium oxide stabilized zirconia composite thermal barrier coating and preparation method technical field The invention belongs to high temperature protection technical field, be specifically related to a kind of silicon carbide-calcium oxide stabilized zirconia composite thermal Barrier coating and preparation method. Background technique [0002] In recent years, gas turbines have developed rapidly. Gas turbine to become a new generation of energy power plant, widely used in It is used in many fields such as energy, power generation, power system and so on. With the increasing power demand of gas turbines and other equipment, More heat is generated, and the important parts in the equipment are affected by high temperature, and their service life and performance have been greatly affected. Earth influence. In order to protect the internal parts of the machine and prolong the service life of the machine, thermal barrier coating as a high temperature...
