Abstract
The utility model relates to an instrument for measuring film adhesive force on the basal body. The utility model is composed of a bottom board 1, a belt pulley 2, a transversal regulating motor 3, a loading motor 4, a loading mechanism 5, a manual lifting hand wheel 6, a locking hand wheel 7, a buffer gear 8, a lifting mechanism 9, a longitudinal regulating knob 10, a belt pulley 11, a two-dimensional motion frame 12, a sample frame 13, samples 14, a diamond indenter 15, a straining rod 16, a horizontal supporting plate 17, a load transducer 18, a bracket 19, a lever 20 and a single trigger 21. The utility model can be used for measuring the film adhesive force of various hard films, ceramic films, softer metal films and polymeric membranes on the basal body, and is especially suitable for various brittleness films with high hardness and various protective films and decorative films of chemical vapor deposition.
Description
Films such as diaphragm, wear-resistant membrane, decorating film are widely used in various product with its excellent performance.In general, except the quality of materials of film, the size of the adhesion of film and matrix is the key factor that influences its usability.The utility model scratch method film adherometer is used for measuring the adhesion of film on matrix exactly.ICL is G01N 19/02, and G01N 19/04.
The part of various engineering goods is owing to wearing and tearing and corrosion cause that initial failure is very huge with scrapping the energy that caused and the consumption of material.In order to protect all kinds of engineering goods, carry out physical vapour deposition (PVD) and chemical vapor deposition plated film new technology at piece surface in recent years, this makes the piece surface characteristic that very big improvement arranged.Adhesion between deposited film and the matrix is the principal element that influences its serviceable life, and present domestic mensuration to adhesion, can only with some more intuitively method detect, as bending method, wearing and tearing method, indentation method and scratch method etc., and these methods all can not get reliable quantitative data.Therefore therefore, adhesion is not gone out quantitative appraisal yet, these methods scarcely have repeatability in addition, and the test to the adhesion of film is inaccurate and incomplete.
In recent years, the criterion that adopts acoustic-emission to scratch abroad as film.Its principle of work is: load, acts on the surface of sample by diamond penetrator, and slides on face to diamond penetrator by loading motor and load transducer.Because sample film all is superhard film (TiC, TiN etc.), under certain critical conditions, the stress of sample film and matrix is greater than the adhesion of film on matrix, film rupture, and the acoustic transmitter probe receives the aural signal of sending when film breaks, and can determine critical load in view of the above.But this method only is applicable to dura mater, then can't receive its signal to mantle.Also have a kind of pressure when paddling on the sample surfaces film with presser sensor original paper pressure-measuring head abroad, pressure signal changed when film was broken, can determine critical load by calculating, but that the shortcoming of this method is a criterion is not obvious.
In order to detect the adhesion of film on matrix fast, accurately, quantitatively, we have developed the scratch method film adherometer.
Film may be defined as the required power in separation unit interface to the adhesion of matrix.Measuring the most reliable method of adhesion is the power that film is separated with matrix of directly measuring, and then calculates the required power in separation unit interface in this process; But it is thin and during with matrix bond more intense, directly assay method is difficult to use, and generally can only adopt indirect method when film.Up to the present, scarification is considered to method preferably.The cut ratio juris is to adopt the very little ball-type hard material pressure head of a tip radius, contact with the solid that is coated with film, and add a load, pressure head streaks from solid surface, so that the critical load of film when coming off is the criterion of adhesion size, can also extrapolate the size of adhesion simultaneously from the value of critical load.
The utility model be with the friction factor of diamond penetrator when face paddles as monitor signal, when diamond penetrator is loaded into certain critical load, the stress between film and matrix is during greater than the adhesion of film on matrix, film rupture; The friction factor that slide between diamond penetrator and face this moment increases suddenly, with the criterion of this catastrophe point as definite critical load.Below in conjunction with accompanying drawing, the utility model is done an explanation.
The utility model (seeing accompanying drawing 1) is by base plate 1, belt pulley 2, horizontal buncher 3, loading motor 4, load maintainer 5, hand-operated lifting handwheel 6, locking handwheel 7, buffer gear 8, elevating mechanism 9, vertical adjusting knob 10, belt pulley 11, two dimensional motion frame 12, specimen holder 13, sample 14, diamond penetrator 15, strain bar 16, horizontal support plate 17, load transducer 18, support 19, lever 20, single card microcomputer 21 is formed.During work sample 14 is placed on the specimen holder 13, energized, loading motor 4 is given power up of lever 20 right-hand members by buffer gear 8, and the lever left end produces a downward power by support 19, this power is by load transducer 18, strain bar 16 arrives diamond penetrator 15, when diamond penetrator touches sample, laterally buncher 3 is started working, and this just drives sample 14 parallel motion to the right on the specimen holder 13, when load reaches a certain critical load, film and matrix are peeled off, this moment, friction force produced sudden change, and the foil gauge in the strain bar is just sent into Computer Processing to this variable signal, showed simultaneously and printed curve (curve is seen accompanying drawing 2).
Determine the criterion of critical load when the utility model scratches friction factor as film, proof does not all have similar products so far both at home and abroad and uses this principle by retrieval.
The utility model adopts the diamond penetrator of R=0.1mm and two kinds of different pressure head radiuses of R=0.2mm, makes analyzer can adopt less load to measure the big sample of adhesion.Like this, to the film of adhesion extra-heavy, can adopt lower load to obtain criterion accurately.The external general pressure head that adopts R=0.2mm, and the pressure head of use R=0.1mm to the film of identical adhesion, only need add 1/4 load, thus enlarged the usable range of this instrument.
Continuous loading of the present utility model is to pass through lever 20 by loading motor 4, is loaded into the diamond penetrator 15 that has load transducer 18, and affacts on the sample 14.The output of load transducer provides single card microcomputer to do load output, the information of the foil gauge output friction force on the load bar (strain bar) is to single card microcomputer, directly obtain the data of load-friction factor by computing, and directly draw out curve, can accurately determine critical load thus by printer.
The utility model is applicable to the mensuration of the adhesion on matrix such as all kinds of hard films, ceramic membrane, softer metal film and polymeric membrane, also can measure the friction factor of any fastness, and sample requirement is simple.The utility model not only can be done production testing for all kinds of film production units, also can do thin-film technique research and use.The utility model is rational in infrastructure simple, and cost is low, is present desirable adhesive force analyzer.
