Vickers Hardness Tester iVick-474M
Brief Introduction:
iqualitrol iVick-474M Vickers hardness tester adopts load cell
control system, improves the precision of the test force and the
repeatability and stability of the indicating value.
iVick-474M shows the test force, dwell time, test numbers on the
screen, only need to input the diagonal of the indentation when
operation, and can automatically get the hardness value and shows
on the screen.
Available to install optional CCD image automatic measuring system
to realize auto vickers measurement.
Application Range:
Suitable for ferrous metal, non-ferrous metals, IC thin sections,
coatings, ply-metals; glass, ceramics, agate, precious stones, thin
plastic sections etc.; hardness testing such as that on the depth
and the trapezium of the carbonized layers and quench hardened
layers.

Principle of Vickers Test:
The Vickers hardness test method consists of indenting the test
material with a diamond indenter, in the form of a right pyramid
with a square base and an angle of 136 degrees between opposite
faces subjected to a load of 1 to 100 kgf. The full load is
normally applied for 10 to 15 seconds.
The two diagonals of the indentation left in the surface of the
material after removal of the load are measured using a microscope
and their average calculated. The area of the sloping surface of
the indentation is calculated. The Vickers hardness is the quotient
obtained by dividing the kgf load by the square mm area of
indentation.
When the mean diagonal of the indentation has been determined the
Vickers hardness may be calculated from the formula, but is more
convenient to use conversion tables.
The Vickers hardness should be reported like 800 HV/10, which means
a Vickers hardness of 800, was obtained using a 10kgf force.
Several different loading settings give practically identical
hardness numbers on uniform material, which is much better than the
arbitrary changing of scale with the other hardness testing
methods.
The advantages of the Vickers hardness test are that extremely
accurate readings can be taken, and just one type of indenter is
used for all types of metals and surface treatments. Although
thoroughly adaptable and very precise for testing the softest and
hardest of materials, under varying loads, the Vickers machine is a
floor standing unit that is more expensive than the Brinell or
Rockwell machines.
