Disgrifiad

Micropits are pits of less than 10 microns depth that are induced by repeated loading cycles in rolling/sliding contact. The data herein is a series of surface / replica surface scans (made using a surface profilometer) for two disks in a twin-disk test rig simulating gear-type contacts. The conditions used in the test were: 1.2GPa max. hertzian pressure (elliptical contact), slide-roll ratio 0.5, entrainment velocity 2m/s.

Surface scans / replica surface scans were made at 0, 6k, 50k, 100k, 200k, 400k, 1 million and 2 million Fast surface cycles (slow surface cycles = 3/5 * fast surface cycles).

Files are supplied as matlab matrices (.mat files), where x is circumferential on the disk, y is transversely across the disk, and z contains the heights of each measured point. Each surface is 6mm in the x-direction with an x spacing of 0.5µm, and profiles spaced at 3µm intervals in the y-direction. units are mm for x and y, and µm for z.

In the file naming FD and SD denote fast or slow surface respectively. in FD cycles, loadstages are as below:

LS00=unrun (0 cycles) - disk surface

LS02=6k FD cycles - replica surface

LS04=50 FD cycles - replica surface

LS05=100k FD cycles - replica surface

LS06=200k FD cycles - replica surface

LS08=400k FD cycles - replica surface

LS10=1 million FD cycles - replica surface

LS12=2 million FD cycles - disk surface

LS12Ac=2 million FD cycles - replica surface
