Abstract
The invention discloses a metallographic specimen and hardness specimen embedding method. The metallographic specimen and hardness specimen embedding method comprises following steps: firstly, specimens are obtained via cutting; the surfaces of the specimens are pressed against an embedding machine workbench; an edge protection embedding material is spread around the specimens; a bakelite powder embedding material is spread around the embedding machine workbench; and at last, embedding specimens are collected after heating and heat preservation. According to the metallographic specimen and hardness specimen embedding method, the edge protection embedding material is spread between the bakelite powder embedding material and the specimens, so that firm combination of the edge protection embedding material with the specimens is realized, specimen edges are protected effectively, falling of surface tissue is not easily caused, and detection accuracy is improved.
Description
Technical field
The present invention relates to metal material metallographic and hardness determination field, particularly the method for embedding of a kind of metallographic specimen and hardness specimens.
Background technology
The sample of the tissue and surface treatment layer depth mensuration detecting skin layer is needed mainly to comprise: cementation zone, nitration case, the coat of metal, decarburized layer etc.
Inlay with single inlay for metallographic and inlaying of hardness specimens, i.e. before bakelite powder.Use single bakelite powder to do hot inlay, although inlay simple, inlay cost low, but protect limit weak effect, mainly inlay and sample are in conjunction with undertighten, and in mill afterwards, throwing process, surface-treated layer easily comes off, owing to coming off, sample detection result often can not represent the actual result of this batch of part.
Also can use single guarantor limit inlay, but it is much higher to protect rim charge cost ratio bakelite powder.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of metallographic specimen of simple and reasonable steps and the method for embedding of hardness specimens; the method for embedding of this metallographic specimen and hardness specimens adopts to add between bakelite powder inlay and sample protects limit inlay; protect limit inlay to be combined with sample closely; energy available protecting sample edge; textura epidermoidea's difficult drop-off, improves detection accuracy.
For achieving the above object, according to the method for embedding that the invention provides a kind of metallographic specimen and hardness specimens, comprise the following steps: first, cut sample; Secondly, the sample face cut is adjacent to pointing machine worktable; Then, guarantor limit inlay is put at sample periphery; Subsequently, bakelite powder inlay is put at pointing machine worktable; Finally, after heating and thermal insulation, sample is inlayed in taking-up.
Preferably, in technique scheme, protect the height 5mm of limit inlay.
Preferably, in technique scheme, put into bakelite powder inlay to inlaying height at pointing machine worktable.
Compared with prior art; the present invention has following beneficial effect: the method for embedding of this metallographic specimen and hardness specimens adopts to add between bakelite powder inlay and sample protects limit inlay; protect limit inlay to be combined with sample closely; energy available protecting sample edge; textura epidermoidea's difficult drop-off, improves detection accuracy.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the method for embedding of existing metallographic specimen and hardness specimens.
Fig. 2 is the schematic diagram of the method for embedding of metallographic specimen of the present invention and hardness specimens.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, the concrete steps of the method for embedding of existing metallographic specimen and hardness specimens comprise:
1, from workpiece, representative position cuts sample 11 (or requiring that position samples according to drawing etc.), and workpiece is very little can directly be inlayed.
2, needing the sample face detected to against pointing machine worktable;
3, bakelite powder inlay 12 is put into the requirement of inlaying height at pointing machine worktable.
4, sample is inlayed by taking out after regulation requirement heating and thermal insulation.
Existing metallographic and inlaying of hardness specimens are inlayed with single inlay, i.e. bakelite powder.Use single bakelite powder to do hot inlay, although inlay simple, inlay cost low, but protect limit weak effect, mainly inlay and sample are in conjunction with undertighten, and in mill afterwards, throwing process, surface-treated layer easily comes off, owing to coming off, sample detection result often can not represent the actual result of this batch of part.
As shown in Figure 2; add between bakelite powder inlay and sample according to the metallographic specimen of the specific embodiment of the invention and the method for embedding of hardness specimens and protect limit inlay, protect limit inlay and be combined with sample closely, energy available protecting sample edge; textura epidermoidea's difficult drop-off, improves detection accuracy.The concrete steps of the method for embedding of this metallographic specimen and hardness specimens comprise:
First, from workpiece, representative position cuts sample (or requiring that position samples according to drawing etc.), and workpiece is very little can directly be inlayed;
Secondly, needing sample 21 face detected to against pointing machine worktable;
Then, a small amount of guarantor limit inlay 22, height about 5mm is put at sample periphery;
Subsequently, bakelite powder inlay 23 is put into the requirement of inlaying height at pointing machine worktable;
Finally, sample is inlayed by taking out after regulation requirement heating and thermal insulation.
To sum up, the method for embedding of this metallographic specimen and hardness specimens adopts to add between bakelite powder inlay and sample protects limit inlay, protects limit inlay and is combined with sample closely, energy available protecting sample edge, and textura epidermoidea's difficult drop-off, improves detection accuracy.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
