                MFT-R4000 high speed reciprocating friction wear tester

                MFT-R4000 is a multifunction tester used for evaluating the high speed reciprocating friction and wear performance of materials and films under different environment with variation of load, frequency, temperature and gas. It is also applied in the friction and wear measurement under corrosive solution, mainly simulating the conditions of sea, river, lake, and body fluid, etc.. 

                    Based on the ball-on-disk friction principle and the auto-control technology, the samples are fixed on the MFT-R4000 tester and the weight or variable loading mechanism was applied on the friction ball. The material samples move reciprocally with high speed at fixed frequency based on the principle of eccentric principle. The curve of the friction coefficient will be obtained by processing the data of friction signal transformed via the A/D converter.
                                             μ=F/N
                                             μ—friction coefficient
                                             F—friction force
                                             N—normal load
                     Friction properties and abrasion resistance of the material or film will be obtained through the change of the friction coefficient curve, i.e., under a specific load, after a certain time (certain distance), the friction coefficient will be changed, in that moment, the film is worn out and the wear volume will be obtained by the weighing method. The high-temperature friction and wear test can be conducted by heating the sample (or tank) with a set temperature.
                    The controlled atmosphere components extract gas through vacuum pumps and gases(N2、He and etc.) are passed in so that samples could be tested in different atmospheres.
                    The section area of wear scar will be obtained directly by measuring the wear depth using the detection component of the wear loss.
                    Electrochemical workstation test components include the electrochemical workstation and liquid tank. The sample is put into the sample vessel and the electrochemical changes in the friction process will be detected through the working electrode (the underneath counterpart as contact electrode) and the reference electrode.
