Table Top Universal Testing Machine
The lab is equipped with Shimadzu’s AG-IS Autograph ® (Shimadzu Scientific Instruments, Columbia, MD) table-top universal material testing system having 50 kN capacity. The machine is capable of testing various materials in tension, compression and bending. The TRAPEZIUM-X software enables to control various test parameters and even low cycle dynamic testing. Data processing in the software is very simple enabling direct calculation of desired mechanical properties such as tensile strength, yield strength, Young’s modulus etc. from the test results.
Shimadzu’s HMV-2T series microhardness tester (Shimadzu Scientific Instruments, Columbia, MD) has automatic load change function with 9 different load to select from. The tested is equipped with Vicker’s diamond pyramid indenter. The automatic operation eliminates operation errors and provides outstanding safety. The superior user interface with LCD touch panel makes the operation simple and easy.
The NANOVEA Tribometer equipment (Microphotonics Inc., CA, U.S.A.) contains accessories to carry out the test in a controlled humidity atmosphere or media such as physiological/lubricating fluids. The instrument follows the ASTM G133-05 tribological testing standard. Testing can be done in a linear reciprocating or rotating disc ball-on-flat configuration. Testing parameters such as normal load, translation speed, total slide distance as well as media temperature may be varied. Data that is acquired during testing consists of compound wear and the coefficient of friction (COF). Additionally, the normalized wear rate and wear mode(s) may be determined from the compound wear and surface imaging of the wear scar, respectively.
Ducom wear testing equipment (Bangalore, India) contains accessories to carry out the test in controlled atmosphere such as physiological/lubricating fluids with precise temperature and humidity control. The instrument also has the capability to test the materials for their wear resistance in linear reciprocating and rotating mode with ball-on-disc or pin-on-disc configuration. The software enables independent selection of various test parameters such as load, speed, distance, temperature, etc. Compound wear (CW) and coefficient of friction (COF) are the main outputs of this unit.
Thermo, Nicolet 6700 FTIR Spectrometer
Fourier Transform Infrared Spectroscopy (FTIR), is a analysis technique that provides information about the chemical bonding or molecular structure of materials, whether organic or inorganic. Unlike SEM inspection or EDX analysis, FTIR spectroscopy does not require a vacuum, since neither oxygen nor nitrogen absorb infrared rays. FTIR analysis can be applied to minute quantities of materials, whether solid, liquid, or gaseous. When the library of FTIR spectral patterns does not provide an acceptable match, individual peaks in the FTIR plot may be used to yield partial information about the specimen.
VCA Optima, AST Products Inc.
The static contact angles of sessile drops of liquids on polished samples can be measured using a face contact angle set-up equipped with a camera. The contact angle data is used for surface properties analysis such as wettability, surface energy, surface tension etc.
It consists of compacting a dry powder in a die at a pressure. Sufficiently high pressure is required to have sufficient strength of the green compact for subsequent handling and processing.
