MFT-4000 Multi-functional Tester for Material Surface Properties

      Over the past decades, the research on material surface has been widely used in national defense, science and technology, industry and agriculture, especially the applications of ion-plating coatings in tools, molds, instrument parts, decoration and etc. has received a lot of economical and social benefits. Therefore, the evaluations of the mechanical properties of the coating are becoming the key to the current coating product-development,and various technical standards of coating products have become the focus of both supply and demand.
Principle of operations:
     The testing of a variety of mechanical properties of the material is achieved by using different components. Different tests such as the indentation test, scratch test, reciprocating friction test, elastic modulus test and roughness measurement can be carried out in this machine.

The indentation test mode:

     It is used to measure the critical load of the adhesive force between the coating and the substrate. The increasing load is applied on the surface of the substrate through the diamond indenter, now the load will be named the critical load which was observed by microscope around the indentation and indicated the failure of adhesive force.

Scratch test:

Reciprocating friction test mode:

     It is used to measure the friction coefficient and wear rate (abrasion resistance) of the coating. Based on the ball-on-disk principle, the weights or variable loading mechanism were applied on the grinding balls, the material sample is fixed on the test stand and the friction pairs can realize the reciprocating uniform linear motion with fixed speed and frequency under dynamic loading or fixed-loaded. The friction coefficient curve under the specific conditions (varied loads and speeds) will be obtained by computing the friction force signal collected by the sensor.

Roughness test mode:

  It is used to evaluate the roughness of the material surface. A micro load (0.05 N) is applied on the stylus which acts on the surface of the coating, while the sample is moved with uniform motion in a straight line. The roughness can be obtained by analyzing the slight fluctuations of the stylus measured through the displacement sensor

The test of elasticity modulus:

    It is used to measure the elasticity modulus of the material surface or coating. The loads are applied on the surface of sample with a double set of loading and unloading rate,the load-depth and unload-depth curve will be obtained by processing the data collected through the displacement sensor. Comparing two sets of data,the modulus of elasticity of the material will be obtained by calculation.

Profilometer:

     It is used to measure the thickness of the coating. A micro load (0.05 N) is applied on the stylus which acts on the surface of the coating, while the sample is moved with uniform motion in a straight line. The thickness of the coating can be obtained from the profile curve between the substrate and the coating, which is derived from the processed data measured through the displacement sensor for the slight fluctuation of the stylus.

Wear rate:

     It is used to measure the cross-sectional area of the wear scar of the material. A micro load (0.05 N) is applied on the stylus which acts on the surface of the coating, while the sample is moved with uniform motion in a straight line. The wear volume of the coating can be obtained from the cross-sectional area of the wear scar, which is derived from the processed data measured through the displacement sensor for the slight fluctuation of the stylus.
