Traditional metallographic specimen preparation method includes: first, carries out sample corase grind on grinder；Secondly, carry out sample fine grinding with a series of varigrained sand paper, fine grinding can on sample grinding machine automatic grinding, it is possible to carry out underhand polish；Again, buffing machine carries out sample polishing；Finally, sample corrosion.For metal matrix ceramic composite coating metallographic specimen, there are the following problems: first, owing to ceramic coating has characteristic hard, crisp, is acted on by grinding force in preparation process, it is easy to occurs to peel off or peel off with metallic matrix, affects coating structure；Second, polishing agent is easily accessible in the crackle formed because of ceramic coating and Metal Substrate stripping, causes experiment effect inaccurate.
Utility model content
The purpose of this utility model is: provide a kind of metal matrix ceramic composite coating metallographic specimen experimental provision preventing ceramic coating from peeling off, damaging.
This utility model is achieved through the following technical solutions: metal matrix ceramic composite coating metallographic specimen experimental provision, including metal matrix ceramic composite coating metallographic specimen, the first pressing plate and the second pressing plate, the first described pressing plate and the second pressing plate are pressed on the upper and lower surface of metal matrix ceramic composite coating metallographic specimen respectively；The first described pressing plate and the second pressing plate equivalently-sized and be all higher than the size of metal matrix ceramic composite coating metallographic specimen；The first described pressing plate and the second pressing plate are bolted, and compress metal matrix ceramic composite coating metallographic specimen.
For preventing from weighing wounded ceramic coating, the first described pressing plate is provided with polypropylene elastic rubber layer near one side and second pressing plate of metal matrix ceramic composite coating metallographic specimen near the one side of metal matrix ceramic composite coating metallographic specimen.
For increasing friction force, prevent metal matrix ceramic composite coating metallographic specimen from sliding, a coarse designs of described polypropylene elastic rubber layer contacting metal base ceramic coating metallographic specimen.
For convenience of clamping, the first described pressing plate and the second pressing plate are provided with the latch closure of convenient clamping.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) metal matrix ceramic composite coating metallographic specimen experimental provision of the present utility model, cooperation by metal matrix ceramic composite coating metallographic specimen, the first pressing plate and the second pressing plate etc., metal matrix ceramic composite coating metallographic specimen can be clamped easily test as an entirety, prevent the peeling of ceramic coating, damage, affect experiment effect.
