Description
Technical field
The utility model relates to austenite stainless steel construction, particularly a kind of austenite stainless steel construction with high rigidity top layer, and uses this to have watchcase, the watchband of the austenite stainless steel construction on high rigidity top layer.
Background technology
Austenitic stainless steel has excellent antiseptic property, extensively adopts in clock and watch part is as gauge stand, watchband, but austenitic stainless steel hardness is not high, is generally 200Hv, if be directly used in clock and watch part, then easily produce scratch, scratches.
The common way of industry applies to be coated with (film) layer (vapor deposition layer as harder) in austenitic stainless steel appearance, or coating (as decoration layers of chrome), thus obtain the austenite stainless steel construction with certain degree of hardness, and use it in clock and watch.But, because these additional painting (plating) layers and austenitic stainless steel basal body structure adhesion are inadequate, during use, easily there is obscission.
Utility model content
In view of this, the utility model provides a kind of austenite stainless steel construction with high rigidity top layer, and uses this to have watchcase, the watchband of the austenite stainless steel construction on high rigidity top layer.
There is the austenite stainless steel construction on high rigidity top layer, the permeable formation comprising an austenite stainless steel matrix and extend towards inside from the surface of this austenite stainless steel matrix.
Alternatively, described permeable formation and described austenite stainless steel matrix are structure as a whole.
Alternatively, the thickness of described permeable formation is 0.1mm ~ 0.15mm.
Alternatively, the thickness of described permeable formation is 0.15mm ~ 0.3mm.
Alternatively, the thickness of described permeable formation is 0.3mm ~ 0.5mm.
The utility model also provides a kind of watchband, and described watchband adopts the above-mentioned austenite stainless steel construction with high rigidity top layer.
The utility model also provides a kind of watchcase, and described watchcase adopts the above-mentioned austenite stainless steel construction with high rigidity top layer.
Compared with prior art, the utility model has the following advantages:
First, the austenite stainless steel construction with high rigidity top layer of the present utility model, for common austenite stainless steel construction, is provided with on its top layer the permeable formation that one deck has high rigidity, antirust, wear-resisting.
Secondly, structurally, permeable formation is using austenite stainless steel construction as matrix, extended towards intrinsic silicon by its surface, it is the some of matrix (i.e. austenite stainless steel matrix), the two is integrative-structure, is different from coating of the prior art or coating or rete (all belonging to additional layer), there will not be obscission in using.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiments, the utility model is described in detail.Should be appreciated that specific embodiments described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model first embodiment provides a kind of austenite stainless steel construction 10 with high rigidity top layer, the permeable formation 12 comprising an austenite stainless steel matrix 11 and extend towards inside from the surface of this austenite stainless steel matrix 11.
In order to remove the relation that permeable formation 12 and austenite stainless steel matrix 11 are described, provide the formation method of permeable formation 12 here.Permeable formation 12 is that the top layer of compound infiltration technology to austenite stainless steel matrix 11 utilizing metallic cementation-nitriding to combine processes, the part on austenite stainless steel matrix 11 top layer is changed into hardened layer, containing the metallic compound that titanium nitride, molybdenum nitride, chromium nitride etc. are stone in the institutional framework of hardened layer, hardness can reach 2200Hv.
Permeable formation 12 is very wear-resisting: permeable formation 12 first have employed metallic cementation composite cementation synchronous with ionic nitriding, and Ti, Mo, Cr in metallic cementation nitrogen in ionic nitriding is combined and defines stone metallic compound; And then Ti-Mo-Cr metal composite is oozed under have employed high vacuum condition, thus obtain hardened layer (i.e. permeable formation 12), reach very high hardness, very wear-resisting.
Permeable formation 12 does not come off: permeable formation 12 is the infiltration layers on austenite stainless steel matrix 11 top layer, it is the some of protocorm (i.e. austenite stainless steel matrix 11), the two is integrative-structure, be different from coating of the prior art or coating or rete (all belonging to additional layer), in using, there will not be the phenomenon that permeable formation 12 comes off.
The antirust function of permeable formation 12: adopt the compound infiltration technology that above-mentioned metallic cementation-nitriding combines, the permeable formation 12 of formation can keep stainless performance.Chromising and nitriding are synchronously carried out, and enable chromium in austenite stainless structure of steel reach balance roughly because of the magnitude of recruitment of chromium when forming reduction and the chromising of compound with nitrogen, can ensure that in stainless steel tissue, chromium content is not less than 13%; Simultaneously by rationally arranging target (Cr-Ti-Mo), even tissue everywhere can be accomplished, ensureing in the scope that organizing after sclerosis still allows at stainless steel tissue everywhere, thus guaranteeing its excellent rustless property.
In using according to reality, the difference of hardness requirement, can change the thickness of permeable formation 12.
When hardness requirement reaches about 1200Hv, the thickness of described permeable formation is 0.1mm ~ 0.15mm.
When hardness requirement reaches about 1600Hv, the thickness of described permeable formation is 0.15mm ~ 0.3mm.
When hardness requirement reaches about 2000Hv ~ 2200Hv, the thickness of described permeable formation is 0.3mm ~ 0.5mm.
In order to better represent the above-mentioned austenite stainless steel construction with high rigidity top layer, below provide several specific embodiment.
As shown in Figures 2 and 3, the utility model second embodiment provides a kind of watchcase 20, and described watchcase 20 comprises austenite stainless steel matrix 21 and permeable formation 22, and the thickness of described permeable formation 22 is 0.1mm-0.15mm.
The utility model the 3rd embodiment provides a kind of watchband, and described watchband adopts the above-mentioned austenite stainless steel construction with high rigidity top layer.
Compared with prior art, the utility model has the following advantages:
First, the austenite stainless steel construction with high rigidity top layer of the present utility model, for common austenite stainless steel construction, is provided with on its top layer the permeable formation that one deck has high rigidity, antirust, wear-resisting.
Secondly, structurally, permeable formation is using austenite stainless steel construction as matrix, extended towards intrinsic silicon by its surface, it is the some of matrix (i.e. austenite stainless steel matrix), the two is integrative-structure, is different from coating of the prior art or coating or rete (all belonging to additional layer), there will not be obscission in using.
The above, it is only preferred embodiment of the present utility model, be not do other forms of restriction to the utility model, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
