Abstract
The utility model discloses a self-lubricating coating steel collar. The self-lubricating coating steel collar comprises a steel collar matrix, the steel collar matrix is coated with a chromium (Cr) layer, a chromium nitride (CrN) layer, a chromium oxynitride (CrCN) layer, a chromium carbon (CrC) layer and a film diamond like carbon (F-DLC) layer in sequence. The self-lubricating coating steel collar is prepared with a nanometer coating in a multi-layer composite structure and with self-lubricating function on the surface of the traditional steel collar, and the nanometer coating is high in hardness, high in adhesion and high in corrosion resistance.
Description
Technical field
The utility model relates to a kind of self-lubricating coat in use rings.
Background technology
Rings is the vitals of winding part on the ring spinner, under the high speed textile state, the defectives such as rings surface can aggravation adhesive wear and fatigue wear occurs, inner track produces the irregular wave Slippage and spot flaking, spinning tension are unstable, broken end during thousand ingots, filoplume are serious, so rings material, surface treatment method, hardness, corrosion resistance, frictional behavior, directly affect the quality index such as resultant yarn filoplume, broken end.
At present, the sheet material processing rings that domestic enterprise adopts No. 20 mild steel more improves case hardness through electrodeposited chromium, but rough surface, it is long to walk the ripe phase, or adopts the Crl5 bearing steel rings, after the heat treatment process, can access higher hardness, but in use corrosion problem is given prominence to relatively.Along with the development of science and technology, various coat rings have appearred, such as plating fluorine rings, have good antifriction characteristic, can directly change up a grade speed of a motor vehicle, but case hardness is low, so limited service life; Diamond like carbon (DLC) rings has high rigidity, high-wearing feature, highly corrosion resistant, but internal stress is high, poor adhesive force, coefficient of friction are higher than plating fluorine rings.
Summary of the invention
In order to overcome defects, the utility model provides a kind of self-lubricating coat in use rings, it is on traditional rings surface, and preparation has the nano coating of multi-layer compound structure and self-lubricating function, and this nano coating has high rigidity, high adhesion force and corrosion resistance.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of self-lubricating coat in use rings, comprise the rings matrix, and be coated with successively Cr layer, CrN layer, CrCN layer, CrC layer and F-DLC layer on the described rings matrix.
As further improvement of the utility model, described Cr layer thickness is 30-50nm, and described CrN layer thickness is 30-60nm, and described CrCN layer thickness is 50-100nm, and described CrC layer thickness is 150-200nm, and described F-DLC layer thickness is 1000-2000nm.
As further improvement of the utility model, described С r layer (1), CrN layer (2), CrCN layer (3), CrC layer (4) and F-DLC layer hardness are 2000-3000HV, and coefficient of friction is less than 0.1.
The beneficial effects of the utility model are: by prepare the multilayer functional coat of good, the low friction of adhesive force, high rigidity, corrosion-resistant, high thermoconductivity on the rings surface, can guarantee that rings is in the high-speed spinning process, spinning tension is stable, and broken end, fibrous index all can be controlled at better level during thousand ingots.
Description of drawings
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the degree of depth-hardness profile of self-lubricating coat in use rings described in the utility model sample test.
The specific embodiment
By reference to the accompanying drawings, the utility model is elaborated, but protection domain of the present utility model is not limited to following embodiment.
A kind of self-lubricating coat in use rings comprises rings matrix 10, is coated with successively Cr layer 1, CrN layer 2, CrCN layer 3, CrC layer 4 and F-DLC layer 5 on the described rings matrix.
Preferably, described Cr layer thickness is 30-50nm, and described CrN layer thickness is 30-60nm, and described CrCN layer thickness is 50-100nm, and described CrC layer thickness is 150-200nm, and described F-DLC layer thickness is 1000-2000nm.
Preferably, described С r layer 1, CrN layer 2, CrCN layer 3, CrC layer 4 and F-DLC layer hardness are 2000-3000HV, and coefficient of friction is less than 0.1.
Get continuous stiffness measurement (CSM) method of self-lubricating coat in use rings use G200 described in the utility model, select two points to carry out impression test at sample, obtain the degree of depth-hardness curve, as shown in Figure 2.
Test condition:
Pressing type: Berkovich tip, pressing numbering: TB13969
Method of testing title: XP, standard CSM method
Impression test depth capacity: 500nm
Impression test is counted out: two impression points of each sample test
