Technical field
The present invention relates to the test unit of fretting wear and the fretting corrosion of mechanical engineering field, relate in particular to a kind of experimental provision of tangential and radial compound fretting corrosionwear.
Background technology
Fine motion (Fretting) refers under the alternate load effects such as mechanical vibration, fatigue load, electric and magnetic oscillation or thermal cycle, nominally the relative motion (displacement amplitude is generally micron dimension) that the amplitude that occurs between static surface in contact is minimum, i.e. fine motion occur in the mechanical part of " fastening " cooperation.It is fretting wear that fine motion can cause the damage of component of machine surface in contact.Fretting corrosion then is in electrolyte (Korrosionsmedium), the corrosion that parts occur in the fine motion process.Tangential and radial compound fine motion is a kind of jog mode that has simultaneously tangential and radial fretting.Tangential and radial compound fretting corrosionwear is prevalent in the fields such as human body implantation piece, petroleum engineering, nuclear power system, therefore, compound inching corrosion wear test device under the exploitation corrosion environment, to slowing down the fretting corrosionwear in the engineering reality, prolong the serviceable life of related components, the reliability part that improves relevant device has great importance.
Summary of the invention
The test unit that the purpose of this invention is to provide a kind of tangential and radial compound fretting corrosionwear, this device can the compound fretting corrosionwear process of truer simulation material under corrosion environment; Can provide for design, manufacturing and the maintenance of the anti-compound fretting corrosionwear of related components and test accurately reference data.
The present invention realizes that the technical scheme that its goal of the invention adopts is, a kind of test unit of tangential and radial compound fretting corrosionwear, and its composition is:
The lower clamp of sample is fixed on the base plate under the clamping, and base plate is fixed on the bottom, test(ing) medium chamber; Test(ing) medium chamber bottom is connected by screw on the fixed friction force deformation support, and on frame, friction force distortion support also links to each other with friction force/displacement transducer on the frame friction force distortion support by screw fastening; Pressure transducer is passed through at the top of the upper anchor clamps of sample successively in the clamping; Vibrator links to each other with the top board of frame; The wear long cross bar of overtesting dielectric cavity of one side of upper anchor clamps links to each other with vertical small end, and the piston rod of transverse hydraulic piston links to each other with the hinge of connecting rod middle and upper part, and the lower end of connecting rod is provided with counterweight;
One side in described test medium chamber is inserted the tip of auxiliary electrode, and the other end of auxiliary electrode is connected with the auxiliary electrode port of electrochemical workstation by wire; The opposite side in described test medium chamber inserts an end of salt bridge, and the other end of salt bridge is connected to the electrolyte solution bottle, and the electrolyte solution bottle is connected with contrast electrode, and the afterbody of contrast electrode links to each other with the contrast electrode port of electrochemical workstation by wire; Described upper sample links to each other with the working electrode port of electrochemical workstation by wire;
Described friction force/displacement transducer, pressure transducer and electrochemical workstation all link to each other with the data collection and control system.
The course of work of the present invention and principle
Lower test specimen is fixed on the lower clamp, and upper test specimen is fixed on the anchor clamps; Regulate again the transverse hydraulic piston and make upper and lower test specimen centering; Then the test specimen that makes progress applies the load of setting, upper and lower test specimen contact.
Injection test medium in the test(ing) medium chamber makes test(ing) medium flood upper and lower test specimen again, the tip of auxiliary electrode, thus upper and lower test specimen is in the corrosion environment of setting.
Then drive upper in the horizontal direction to-and-fro movement of test specimen by the transverse hydraulic piston by connecting rod, cross bar, upper anchor clamps; Simultaneously, drive upper in the vertical direction to-and-fro movement of test specimen by the vibrator on the top board by pressure transducer, upper anchor clamps.Thereby make test specimen, lower test specimen that tangential (level) and (vertical) compound fretting corrosionwear radially occur in corrosion environment.
In compound fretting corrosionwear process, tangential force (friction force) when friction force/displacement transducer goes out tangential and radial compound fine motion by the deformation Real-Time Monitoring of monitoring the friction force support, the pressure transducer Real-Time Monitoring that links to each other with vibrator goes out exciting force, send the data collection and control system to process; Simultaneously, electrochemical workstation also send the galvanic corrosion data data collection and control system to process.Analysis draws data and the rule of fretting wear under the corrosion environment.
Change test(ing) medium, electrolyte solution, given different compound fine motion parameter can be carried out the tangential and radial compound inching corrosion wear test under the different operating modes.And then draw the reciprocation of fretting wear and corrosion under corrosion environment.For the upper and lower test specimen of difformity and size, adopt corresponding upper and lower anchor clamps can finish test.
Compared with prior art, this real beneficial effect of the invention is:
This device can be realized the tangential and radial compound fine motion of upper and lower test specimen in different corrosion environments, and the parameter of tangential fine motion and radial fretting can be set separately; Thereby can carry out the compound inching corrosion wear test under the various operating modes more authentic and validly.And then draw the reciprocation of fretting wear and corrosion under corrosion environment.Can be for the anti-compound fretting corrosionwear design of the related components under corrosion environment, moved, make and safeguard to provide and test accurately reference data.
