A reciprocating type ball-on-disc tribometer was used to measure the tribological behaviour of the thermally sprayed cobalt oxide coatings against the alumina (Ø 6.35 mm) counterface. After wear testing at high temperatures, the area of the wear tracks was 300 μm² measured by a white light microscope. The following parameters were used for sliding wear testing. Parameters Applied load (N) Sliding velocity (cm/s) Test frequency (Hz) Track length (mm) Total sliding cycles Total sliding distance (m) Values 10 3.14 1 10 2500 50 Determine the wear volume in mm³ that was removed during the sliding process and the specific wear rate (mm³/N.m.).

How do i find the tolerances from standard tables for H7 and s6? The answer should be: For H7 (hole) at diameter 50 mm: Upper deviation (ES): +25 µm Lower deviation (EI): 0 µm For s6 (shaft) with diameter 50 mm: Upper deviation (es): +59 µm Lower deviation (ei): +43 µm

True/False The self-preserving size distribution for particles undergoing thermal coagulation generally has a geometric standard deviation of about 1.3.

A GO/NO-GO snap gage is required to inspect the diameter of a shaft that is 1.000 ± 0.020. A wear allowance of 2% of the entire tolerance band is applied to the GO side. Determine (a) the nominal sizes of (a) the GO gage and (b) the NO-GO gage
