Abstract
The invention discloses a pressure tester for producing the larger-area micro deformation of a nitride coating. One side of the upper surface of a stand is connected with a pressure rod bracket which is horizontally and vertically connected with one end of the pressure rod. The 1/3 position, away from the fixed end of the pressure rod, of the pressure rod is vertically downwards connected with a hard alloy pressure head, and the other end of the pressure rod is connected with a scale pan by a steel wire rope; and a sample rod is arranged below the hard alloy pressure head, and is supported and fixed by a sample rod bracket. The pressure tester has the technical effects that: the pressure tester has a simple structure and low cost, and is easy to operate and convenient to use; samples with different micro deformations can be obtained according to needs; and the deformed nitride coating can be observed through a transmission electron microscope by treatment.
Description
Technical field
The present invention relates to a kind of pressure testing machine, relate in particular to a kind of Manual pressure testing machine that makes nitride coatings produce larger area microdeformation.
Background technology
The method of conventional research nitride hard coating microdeformation is Using Nanoindentation both at home and abroad at present.After coating nano-indenter test, the region of coating distortion is very little, is conventionally less than 1 square micron, the preparation distortion plane of coating or the sample for use in transmitted electron microscope in cross section, can find the probability of coating impression deformed region extremely low, be difficult to carry out the preparation of transmission electron microscope sample.A kind of pressure testing machine that makes nitride coatings produce larger area microdeformation, it is a kind of manual pressure testing machine, adopt lever principle, can produce on nitride coatings surface the deformed region of 1-6 square millimeter, by loading the counterweight of Different Weight, can obtain the local nitride coatings that different distortion occurs.This testing machine structure is simple, and cost is low, easy to operate.
Summary of the invention
A kind of Manual pressure testing machine that makes nitride coatings produce larger area microdeformation of the present invention, can obtain the sample of the part generation diverse microcosmic distortion nitride coatings that can be used for transmissioning electric mirror test by demand, have important actual application value.
The present invention is achieved like this, it comprises support, press rods support, press rods, wimet pressure head, specimen holder, specimen holder support, wire rope, scale pan, a side that it is characterized in that the upper surface of support is connected with press rods support, one end of the vertical Bonding pressure bar of press rods support level, press rods is connected with wimet pressure head vertically downward from stiff end 1/3 place, the other end of press rods connects scale pan by wire rope, the below of described wimet pressure head is provided with specimen holder, and specimen holder is fixed by specimen holder stent support.
Technique effect of the present invention is: simple in structure, cost is low, and easily operation, easy to use, is widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Support 2, press rods support 3, press rods 4, wimet pressure head 5, specimen holder 6, specimen holder support 7, wire rope 8, scale pan in the drawings, 1.
Embodiment
As shown in Figure 1, the present invention is achieved in that support 1 is to be welded into the round steel that 12 diameters are 30mm the cube shaped steel structure frame that a length of side is 1000mm, forms the frame of this testing machine.On support 1, plane two length of the vertical welding in round steel middle part are on one side that 200mm diameter is the round steel of 50mm, its spacing is 150mm, and make a call to respectively in these two round steel upper ends the through hole that a diameter is 30 mm, and make these two through holes be total in the horizontal direction axial line, axial line is 1100mm apart from the distance of level ground, and the axial line of two vertical round steel intersects therewith, by a length, be that intert in two holes and free to rotate at two ends that 210mm diameter is slightly less than the round steel of 30mm, two vertical round steel and rotatable round steel formation press rods support 2.Round steel at a long 1100mm of diameter 30mm of press rods support 2 round steel middle part vertical welding free to rotate is press rods 3.When press rods 3 level, apart from its stiff end 1/3 place, weld vertically downward the wimet pressure head 4 of a diameter 20mm, wimet pressure head 4 other ends are truncated conical shape, round platform length 20mm, and the diameter of lower end disc is 2mm,, wimet pressure head 4 total lengths are 85mm.During press rods 3 horizontal positioned, the bar shaped steel that a width and thickness are 50mm is set in the position apart from pressure head end face 2mm, bar shaped steel upper and lower surfaces are parallel with surface level, during experiment, sample is placed on the bar shaped bar of pressure head below, therefore bar shaped steel is called again specimen holder 5, specimen holder 5 two ends are welded on support 1.The round steel that a diameter is 30mm is welded at middle part at specimen holder 5 vertically downward, and when testing machine is not worked, its lower end just can touch level ground, is specimen holder support 6.In press rods 3, apart from its stiff end 2/3 place, be equipped with a through hole, wire rope 7, by hanging scale pan 8 in its two ends system after this through hole, adds counterweight during experiment as required in scale pan 8.This testing machine uses lever principle to make wimet pressure head produce large pressure at coating surface, makes the local larger area deformed region that produces of nitride coatings, by processing the structure that can utilize transmission electron microscope research nitride hard coating microdeformation.
