Features:

a) Compact, benchtop instrument with inline microscope.

b) Automated load control (continuous, fixed and ramp).

c) Automated scratch test profile: Software controlled movement of test specimen along X and Y axis for unidirectional scratch, bidirectional scratches and scratches at different location on the specimen.

d) Acoustic emission sensor to detect early damage of the coating.

e) Environment chamber: Lubricant corrosion cup with temperature control for testing biomaterials at physiological conditions.


Resolution/Specification:

a. Force (normal and tangential) = 2 to 200 N
b. Loading Rate = 0.01 to 20 N/s
c. Multi-axis stage = x-axis, y-axis travel 75 mm (min)
d. Linear stage = travel 75 mm (min)
e. Stroke (X) = 0 to 50 mm (100 micron resolution)
f. Speed = 10 micron/s to 5 mm/s
g. Sample size =
h. Scratch stylus =
i. Indentation stylus =
j. Optical imaging =
k. Acoustic emission =


List of Facilities:

• Scratch loading (constant, progressional, incremental)
• Scratch motion (single, multiple scratches, bidirectional)
• Full control of length, speed and loading rate
• Instrumented indentation


Application domains:

• Critical load of hard and brittle coatings like titanium nitride, ceramics
• Determination of working load limit of soft coatings like PTFE and other polymers
• Identification of process parameters of heat treatment for best scratch resistance
• Estimation of bond strength at substrate - coating interface
• Product development and quality control of surface engineered products
