The equipments is designed for surface testing of different on properties materials by means of physical and mechanical characteristics measurement in micro and nano volumes using depth sensing indention and scratch testing. The measurement results indention and registration is carried out in automatic mode. This is the only way for assessment of micro hardness, elasticity module and other micro mechanical characteristics of small samples and thin surfaces.
The depth sensing indention method is based on automatic registration of load on indentor and depth of its indention. Results are presented in the form of indention diagrams. Their processing allows us to determine the materials micro hardness and elasticity module, to study the materials micro deformation peculiarities on the indention kinetics, to register the materials creep flow.
The scanning indention (scratching) method is based on continuous registration of resistance to indentor movement along the surface with a specified load. Determination of statistical connections between resistance of local material volumes to contact deformation allows us to carry out the complex assessment of the surface layer state on the track of scanning: to assess an average strength along the track of scanning, to asses heterogeneity of strength properties, to simulate elementary acts of friction and wearing out processes, to assess the coatings adhesion.
Methods of nano indention are used in scientific laboratories in case of research of physical and mechanical surface properties and ultra fine near surface material layers. They are widely used in machine building and metallurgy as well as in micro electronics (properties of semiconductors, substrates), medicine (properties of prosthesis, tooth stopping, bone tissue), biology (plant tissue characteristics), fuel and lubrication materials (oil carrying capacity) etc.
