EQ-RHT50-32-LD is high throughput, automatic 32-sample Rockwell hardness testing system for high throughput new alloy development and process optimization. The station integrates a Rockwell hardness tester probe with XY stage, 32-sample station, and laptop remote control. It enables quick, easy, and accurate hardness testing of samples without the need of material-dependent calibration. The measured HV hardness can be automatically converted to HB, HRA, HRB scales. A 50 N test load probe is included for hardness tests ranging from 19 - 70 HRC (35 - 1000 HV).
SPECIFICATIONS
Features
The high throughput Rockwell hardness testing system consists of:
Hardness tester probe with 50 N test load for 19 - 70 HRC (35 - 1000 HV) test
Hardness tester probe holder and triggering mechanism
XY stage system and its control box
32-position sample stage
Laptop with pre-installed control and analysis software
The automatic operation improves efficiency, reduces time, and minimizes operator related error
Fast, automatic hardness testing and analysis of 32 samples (~20 min), and automatic output of hardness data via a USB port
The hardness testing system can be upgraded with 1D line scan and 2D mapping scan features at extra cost
Please contact MTI for system customization, such as sample stage with different dimensions, integration of the station with a glove-box, etc
Test Method
Portable Rockwell static test method: a diamond indenter is forced into the sample and the indentation depth is automatically analyzed to determine the hardness.
The indentation depth is continuously measured while a load is applied and released. From the depth difference between pre-load and total load conditions (See the first photo below), sample hardness is determined
Compared to traditional rebound and ultrasonic hardness testing method, TIV method does not require Young's modulus calibration for different materials, enabling direct, fast, and accurate measurement of sample hardness
Probe
A tester probe with 50 N test load is included for 19 - 70 HRC (35 - 1000 HV) test
Measuring time: ~5 - 10 sec
USB interface for test data output and remote control
A digital camera with a laser pointer is integrated for indicating the hardness testing spot on the sample surface and recording the testing spot by saving the image
