4 µn mn kn High Precision Modular Easy to Upgrade What are Various Test Scales Tribometer is an instrument that measures friction, wear, coefficient of friction i.e. tribological properties between two surfaces in contact. Dependent on the load and environmental range it can be categorized into several areas such as: Nano tribometer - tribometer that works at low and ultra low load range. Vacuum tribometer - tribometer that performs testing under vacuum condition. Fretting tester - tribometer that al-lows to perform high speed testing under small oscillatory dis placement. Ultra high torque tribometer - for testing materials, samples that generates ultra high friction. Industrial Tribometer - tribometer that can run tests close to real life scenario. It can simulate real con ditions, mount real components etc. Lubricant Tribometer - tribometer that is specifically designed to run lubricant, greases, anti fric-tion coating etc. Rtec Universal Tribometer This is a multi functional tribometer has interchangeable modules and load cells, that allows it to run several tests on same platform. Rtec Load Cells Rtec manufactures several pat-ented load cells. The tester al-lows to interchange load cells easily. With this concept it can achieve nano, micro, macro tribology ranges and still maintain highest resolution and accuracies associated with each load cell. Load Cell Categories Each of these load cells type are available in nano, micro and macro ranges. Piezo load cell - for highest data acquisition in reciprocating mode. 2 dimension load cell - for ease of use for low and mid range loads. 1 dimension load cell - to de-couple friction and down force sensors. Ideally suited for high performance. 6D load cell - to measure force in all axis Torque sensor - to measure torque

6 Optimized for any sample and multiple applications The tester comes with a widee range of surface inspection modules. Combination choice depends on the application. Same area of the sample can move between different techniques automatically. The combination of various techniques on one platform allows to exploit advantages of all methods on one tester. lnline Profilometer with Automatic Stitching Confocal Spinning disc (Nipkow) confocal technology for fast vertical scanning Best technology for surface and sub-surface feature measurement, full field 3D characterization of steep slope analysis (Maximal slope: 72 vs. 44 from Interferometry) Highest lateral resolution in optical profiling.

Using interchangeable chambers a wide range from -120 to l200c, controlled humidity, vacuum up to 10-7 Torr etc. is achieved. Few setup also allows to heat both upper and lower sample separately to simulate real life situations. 1000C 1000C The advanced temperature controller allows to measure temperature at multiple points simultaneously. All the chambers are close loop and the requested conditions are controlled using the software automatically. The PID for different range of chambers are automatically loaded once an option is mounted. -60C 10-7 Torr Vacuum Uniformity -120 to 1200 ( Humidity Vacuum 10-7 Torr 500C 150C Close Loop Humidifier Temperature Controller 1000C

8 Combination of various data channels such as Friction, Displacement, 3D sub-nm Images, Acoustic emission, Electrical Contact Resistance, Temperature, Humidity, Torque etc. allows to get comprehensive data analysis, that in turn allows to come to conclusive answers. - - _j :---- Friction/ Torque Torque, friction, coefficient of friction are recorded and displayed in real time. Acoustic Emission The acoustic emission signal indicates initia tion of failure at the test interface. The sen sor uniquely filters out the motor and ambi ent noise and shows the inter-facial acoustic signal. Down Force Down force is recorded and displayed in real time. This test shows step increase in down force. The force can be controlled in constant, linear or custom mode. ECR Electrical contact resistance sensor measures the surface electi cal properties. Different resis tance range is available from few milli ohms to mega ohms.

10 Coating, Materials Testing Scratch Scratch test The scratch test is done to calculate adhesion, scratch hardness of coatings. With the advent of new deposition methods and technologies thinner coatings are finding its way in every aspect of our life. Coatings are present on LCD displays, phones, cut ting tools, mems, glass, automobiles, devices etc. The quantita tive coating adhesion scratch test is a simple practical test that has been around for a long time. But reliable, reproducible and comprehensive test requires careful control of the test system configuration and testing parameters. The scratch test requires applying a load on the sample that needs to be tested with a spherical tip or a custom tip. During the process of applying the load the sample is moved at a constant velocity and several parameters such as Friction (Fx), Down force (Fz), Coefficient of friction (COF), displacement (Z), acous tic emission (AE), temperature etc. are measured In situ. nm to mm Thick Coatings High Temperature About tester The scratch module can run both scratch adhesion and scratch hardness test. Each axis X,Y,Z have encoders and are closed looped. The down force is controlled in real time. The tester can be used to scratch coatings from nm to several microns. Its extremely easy to use and can be pre programmed for repetitive test or make custom test for advance analysis. Features X, Y or combination direction scratch Close loop controls Multiple test locations/ samples Multiple load range Environmental control chambers Dry or in Liquid lnline Imaging lnline Imaging The sample automatically moves under optical profilometer and /or AFM and creates a complete 3D image by stitching across entire track. The optical profilometer is optimized for scratch test. The profilometer head can be a white light interferometer and confocal microscope combination. The combination allows to measure steel scratch slopes, trans-parent coatings (glass etc) and measure roughness, volume wear, method of failure etc. with sub nm resolution.
