Description of drawings
Fig. 1 is a sectional view, and a preferred embodiment of the present invention's wear-resisting chain is described; And
Fig. 2 is a Raman spectrum analysis figure of one of this preferred embodiment wearing layer.
Embodiment
About addressing other technology contents, characteristics and effect before the present invention, in the following detailed description that cooperates with reference to one of a graphic preferred embodiment, can clearly present.
As shown in Figure 1, this preferred embodiment of the present invention's wear-resisting chain 2 comprises a chain body 21, and a wearing layer unit 22.This chain body 21 comprise most in foreign ministers go here and there folded chain link 211, most in order to should majority chain link 211 serial connection all-in-one-piece chain pins 212, most ring set respectively is at the lining on one of this majority chain pin 212 side face 213, the most chain roller 214 of ring sets on one of this majority lining 213 side face respectively, an and wearing layer unit 22.
Each chain link 211 has the right chain sheet 215 of two-phase septal surface.Each chain pin 212 is in order to adjacent two chain links 211 are combined, and each chain pin 212 mainly is four folded chain sheets 215 of foreign minister in running through; Wherein, chain pin 212 is and folds in outer two chain sheets, 215 drive fits, and opposite two terminations are that the difference rivet clasp is at these two chains sheet, 215 places; But chain pin 212 is to be loose fit with the two chain sheets of folding in interior 215.Moreover each lining 213 is to be nested with on the corresponding chain pin 212 of institute, and its opposite end portion pierces into corresponding string respectively to fold in two interior chain sheets 215 tightly.And each chain roller 214 is rollably to be nested with on the corresponding lining 213 of institute, and its opposite end face is that the corresponding string of conflicting is respectively folded in two interior chain sheets 215.
This wearing layer unit 22 is to have most wearing layers 221, and this majority wearing layer 221 is the surfaces that are coated on all chain sheet 215 surfaces, all chain pin 212 surfaces, all linings 213 respectively, on the surface of all chain rollers 214.And each wearing layer 221 is a thickness between between 0.01 micron (μ m)～10 microns, and friction factor is between 0.01～0.65, and have high hardness (HV 900-9000), abrasion resisting, the class of characteristic such as the surface lubrication degree is good, anti-oxidant, corrosion-resistant, adhesive quality is good bores carbon (Diamond-Like Carbon, DLC) film, that is to say, wearing layer 221 is class graphite key (Graphite-likeBond, or sp
2Bond) with class diamond key (Diamond-like Bond, or sp
3Bond) the amorphous carbon film person of combination, and can divide into the pure carbon class and bore carbon, bore two kinds in carbon with the class that contains non-carbon, wherein the non-carbon of indication is can be selected from: hydrogen (H), nitrogen (N), silicon (Si), oxygen (O), fluorine (F), tungsten (W), titanium (Ti), chromium (Cr), molybdenum (Mo), niobium (Nb), tantalum (Ta), ruthenium (Ru), iron (Fe), cobalt (Co), nickel (Ni), aluminium (Al), copper (Cu), gold (Au), silver (Ag), and these one of combination.
Moreover, this majority wearing layer 221 is to see through Low Pressure Chemical Vapor Deposition (ChemicalVapor Deposition, CVD), physical vaporous deposition (Physical VaporDeposition, coating technique such as PVD) is to be coated on respectively on chain sheet 215, chain pin 212, lining 213 and the chain roller 214.
In simple terms, the principle of Low Pressure Chemical Vapor Deposition, mainly be to allow contain hydrocarbon gas (as methane, acetylene, hydrogen etc.) cracking generation carbon or hydrocarbon atom, ion or free radicals under the effect of electricity slurry, and on chain sheet 215, chain pin 212, lining 213 and chain roller 214 surfaces, adhere to, deposit formation one wearing layer 221 respectively.Wherein, CVD commonly used has direct current slurry enhanced CVD (DC Plasma Enhanced CVD, DC-PECVD), radiofrequency plasma enhanced CVD (Ratio Frequency Plasma Enhanced CVD, RF-PECVD), microwave electricity slurry formula CVD (Micro Plasma CVD, MPCVD), electron cyclotron resonace formula CVD (ElectronCyclotron Resonance CVD, ECR-CVD), light assisted CVD (Photo AssistedCVD, Photo CVD) ... Deng.
In addition, with physical vaporous deposition, be in vacuum or contain under the environment of inert gas (as helium, argon gas), shine Coating Materials with ion bombardment or with high electric current by Coating Materials (as graphite target) or with high-octane light, so that it forms gas-phase carbon atom, carbon ion, on chain sheet 215, chain pin 212, lining 213 and chain roller 214 surfaces, to adhere to, to deposit formation one wearing layer 221 respectively.Wherein, Chang Yong PVD has arc discharge method (ArcDi scharge), laser stripping plating method (Laser Ablation), sputtering method (Sputtering), ion vapour deposition method (Ion Platting) ... Deng.
As shown in Figure 2, because wearing layer 221 person that is the quasi cobalt carbon diaphragm, when utilizing Raman spectrometer (Raman Spectroscopy) that wearing layer 221 is carried out structural analysis, can produce a graphite characteristic peak (Graphite peak, be called for short G peak) and an out-of-sequence characteristic peak (Di sorder peak, be called for short D peak), these two characteristic peak appear at 1520～1600cm usually respectively
-1, 1330～1360cm
-1The place; In the present embodiment, wearing layer 221 is after the Raman spectrum structural analysis, and its G peak appears at 1580cm
-1The place, and D peak appears at 1350cm
-1The place proves that wearing layer 221 is DLC structure person really.In fact, see through Raman spectrometer and detect, confirm that the structural characteristics of quasi cobalt carbon diaphragm is (as its existing sp
2, sp
3Few more than the bond) know-why and Operations Analyst, be to have in this technical field to know usually that the knowledgeable knows and widely used, no longer carefully state in this.
Therefore, see through that 221 of wearing layers can present high hardness, abrasion resisting, high surface lubrication degree, adhesive quality is good and corrosion resistant structural characteristics, can be to excellent protection effects of parts performance such as chain sheet 215, chain pin 212, lining 213 and chain rollers 214, and allow these wear-resisting chain 2 integral body can produce abrasion resisting, corrosion-resistant, high lubricated, with effect such as relative growth working life.
Be noted that in addition, this wearing layer unit 22 also can be to be coated on the part of this chain body 21, for example: in parts such as chain sheet 215, chain pin 212, lining 213 and chain roller 214, to choose any one kind of them, to choose wantonly two kinds or optional three kinds, and the mode that number of components is not limit is bestowed coating processing, certainly, the quantity of the wearing layer that forms 221 is to decide along with the quantity for the treatment of the coating parts, describes the mode of execution person who deposits a wearing layer 221 on the surface of all chain sheets 215, chain pin 212, lining 213 and chain roller 214 respectively so be not limited in present embodiment.
In sum, the present invention's wear-resisting chain 2, see through and be coated on chain sheet 215, chain pin 212, lining 213 and chain roller 214 lip-deep anti-retes 221, be for have high hardness, low coefficient of friction, abrasion resisting, high surface lubrication degree, adhesive quality is good and the diamond-like carbon film person of characteristic such as corrosion-resistant, make made wear-resisting chain 2 can produce abrasion performance, anticorrosive, high surface lubrication, and effects such as long service life, so can reach the present invention's purpose really.
The above person of thought, only for the present invention's preferred embodiment, when the scope that can not limit the invention process with this, promptly the simple equivalent of being done according to the present patent application claim and invention description content generally changes and modifies, and all still belongs in the scope that patent of the present invention contains.
