Abstract
The present invention discloses a ceramic coating scraper and a processing technology thereof. The scraper is formed by processing a steel chip scraper. The cutting edge of the scraper is composed of the cutting edge base body of the steel chip scraper, a nickel and aluminium alloy layer and a ceramic coating, wherein the nickel and aluminium alloy layer with thickness of 20 to 80 um and width of 6 to 14mm is directly coated on the cutting edge base body; the nickel and aliminium alloy layer is coated with a ceramic layer whose thickness is 130 to 300 um. The ceramic coating scraper has the advantages of wear resistance and high temperature resistance. The service life of the ceramic coating scraper is 7 to 13 times the steel chip scraper. The ceramic coating scraper can greatly improve the efficiency of paper making.
Description
Technical field
The present invention relates to a kind of scraper with ceramic coating and manufacture method thereof that is used on the coating machine.
Background technology
Scraper is the critical component of paper-making industry common equipment coating machine, and the quality of scraper directly has influence on product quality and production efficiency.Traditional coating blade is a kind of through the peroxidating surface-treated spring steel blade that turns blue, and in use quick abrasion, life-span are short for it, need frequent tool changing, and the rate that comes into force is low.
Summary of the invention
The purpose of this invention is to provide a kind of coating machine scraper with ceramic coating that can significantly improve service life.
Scraper of the present invention is design like this: the ceramic coating scraper is to be made through processed by the steel disc scraper, its cutting edge is made up of steel disc scraper edge matrix, nickel alumin(i)um alloy layer, ceramic coating, the nickel alumin(i)um alloy layer directly is coated on the blade matrix, thickness is 20-80um, width 6-14mm applies the ceramic layer of one deck 130-300um thickness again on the nickel alumin(i)um alloy layer.
Can adopt following ceramic coating scraper processing technology:
1, the blade matrix is handled.With blade surface sandblast oil removing, removing oxide layer.
2, spraying nickel alumin(i)um alloy layer.On the blade matrix of handling, spray Nickel Aluminium Alloy Powder, coating thickness 20-80um, width 6-14mm, the blade substrate temperature is controlled at 80-120 degree centigrade during spraying; Speed: 400-520 meter per second.The Nickel Aluminium Alloy Powder composition is: aluminium 20%; Nickel 80%.
3, ceramic coated layer.Subsequently, on the nickel alumin(i)um alloy layer, spray the graded ceramics powder again, coating thickness 300-400um, spraying rate 400-520 meter per second, during spraying blade substrate temperature: 80-120 degree centigrade.The ceramic powder composition is: alundum (Al 60-80%; Zirconia 7-10%; Carborundum 8-30%.
4, milled processed.After the cooling, the ceramic coating of blade is carried out milled processed, ceramic coating grinds off 70-150um.
5, check warehouse-in.
Ceramic coating scraper of the present invention is wear-resisting, high temperature resistant, and hardness reaches HV850-1300, and bond strength reaches 50-108PMa, and be 7-13 times of steel disc scraper its service life, can improve the efficient of paper greatly.
The specific embodiment
Below ceramic coating scraper of the present invention is further described in detail.
The ceramic coating scraper is to be made through the blade surface processed by the steel disc scraper.At first, the blade matrix is handled blade surface sandblast oil removing, removing oxide layer.Then, on the blade matrix of handling, spray Nickel Aluminium Alloy Powder, coating thickness 80um, width 8mm, the blade substrate temperature is controlled at 100 degrees centigrade during spraying: speed: 500 meter per seconds.The Nickel Aluminium Alloy Powder composition is: aluminium 20%; Nickel 80%.Then, ceramic coated again powder on the nickel alumin(i)um alloy layer, coating thickness 300um, spraying rate 500 meter per seconds, temperature: 100 degrees centigrade.The ceramic powder composition is: alundum (Al 70%; Zirconia 10%; Carborundum 20%.After treating blade cooling, the ceramic coating of blade is carried out milled processed, the ceramic coating 150um that regrinds.At last, check warehouse-in.
