Abstract
The invention discloses a method for improving plasma sprayed ceramic coatings and base binding strength, which is sprayed ceramic coating fusion processing method. The method is that sceramic coatings which are prepared by plasma spraying are put in special environment which is 300-550 DEG C for 4-8 hours and then is cooled along with a stove. The coatings and a workpiece base are mutually diffused or are formed into a new phase, thereby playing a role of a transition layer between the coatings and the base. The bonding strength of the coatings and the base are improved by about 20 percent and is capable of meeting the application requirements for industries.
Description
One, technical field
The present invention relates generally to industry steel field of surface coatings commonly used, specifically relates to the method that improves steel surface and plasma spraying ceramic coat bonding strength.
Two, background technology
In recent years, plasma spraying technology is widely used in every field with the performance such as corrosion-resistant, wear-resistant of its excellence, still, because spraying coating process itself has determined coating inside to have some defectives such as hole, crackle and has inevitably had remaining internal stress.Coating and high base strength are lower, are generally about 30MPa, reduce the work-ing life of coating, restriction coatings applications scope.Therefore, people are devoted to improve the research of coating and substrate combinating strength always, but produce little effect.At present, the Chang Yong raising coating and the method for substrate combinating strength have:
(1) the workpiece pre-treatment treats that to workpiece coatingsurface carries out roughening treatment and thermal pretreatment etc. in various degree before being included in spraying.
(2) method of process modification is also a lot, thereby as reducing physicals difference between coating and the matrix by increasing transition layer, making the unrelieved stress of coating obtain the lax substrate temperature that improves in anchoring strength of coating, control coating thickness and the spraying process to obtain the good binding performance.
(3) the coating aftertreatment is by means such as certain machinery, physics, chemistry or thermal treatments coating to be processed, and to change coating structure, improves coating performance, as oxide treatment, sealing of hole processing, remelting processing etc.
Consider that disbonding inefficacy major cause is that matrix and coating's adhesion are low, manage to make and form a kind of new thing between coating and matrix mutually or the phase mutual diffusion, make it to play transitional function at crystalline structure and rerum natura, to improve coating and high base strength with matrix and coating.
Three, summary of the invention
1, goal of the invention
The object of the invention provides a kind of method-plasma spraying ceramic coat fusion treatment method that improves plasma spraying ceramic coat and substrate combinating strength
2, technical scheme
A kind of method that improves plasma sprayed ceramic figure layer and substrate combinating strength is characterized in that it is to adopt plasma spraying method at carbon steel work-piece surface spraying NiCrAl or NiCr bottom, uses Cr again

3The ceramic coating of spraying working lining, wherein X=0～50%; The furnace atmosphere environment of then the carbon steel work-piece matrix being put into 300 ℃-550 ℃ is incubated 4 hours-8 hours down, furnace cooling.
3, beneficial effect
After fusion treatment, form a kind of new thing mutually between coating and workpiece substrate, between coating and matrix, work to be coating, can make the bonding force raising about 20% of coating and matrix.With plasma spraying Cr
2O
3-8%TiO
2Ceramic coating is an example, insulation is 4 hours under 450 ℃ of oxidizing atmosphere environment, and transition layer, ceramic coating microhardness improve 31%, 25% respectively, and bonding strength has improved 20%, see Table 1, wherein the bonding strength measuring method is pressed the execution of ASTM-C633-2001 standard.
Coating microhardness, bonding strength before and after 450 ℃ of fusion treatment of table 1

The reason that improves for anchoring strength of coating after the fusion treatment mainly contains following two aspects:
1, coating substance phase change
Measure processing front and back coatingsurface thing mutually as shown in Figure 1 by X-ray diffraction analysis, as can be known, through after the fusion treatment, variation has taken place in coatingsurface thing mutually, by original C r
