Ceramic overflow pipeline inner wall wear-resistant coating

Abstract

The invention discloses a ceramic overflow pipeline inner wall wear-resistant coating which is prepared from the following components in parts by weight: 15-32 parts of Cr3C2-NiCr, 18-33 parts of WC-Co, 26-41 parts of NiCrBSi, 16-25 parts of silver-base solder, 11-17 parts of TaC and 13-19 parts of NbC. The ceramic overflow pipeline inner wall wear-resistant coating has the advantages of wear resistance, high temperature resistance, high compactness, high bonding strength, simple process preparation and flexible operation, and is suitable for painting the ceramic overflow pipeline inner wall.

Description

technical field

[0001] The invention specifically relates to a wear-resistant coating on the inner wall of a ceramic overflow pipe. Background technique

[0002] Due to the long length

[0003] In the long-term erosion and wear state of high-hardness particles in the fluid, the pipeline and its elbows will suffer from abrasive damage or corrosion damage. especially

[0004] Especially when transporting solid-phase material fluid, the pipe elbow is washed by the high-speed solid particles, and the wear is more serious, causing system safety.

[0005] Faults, increased repair and maintenance costs. Contents of the invention
