The influence of Surface Roughness on Instrumented

It shows that if the maximum penetration depth is higher than 20 times the roughness Ra,the surface can be considered as flat for such load.Finally,the force-penetration depth curves for the rough sample shown in Fig.6 confirm the better repeatability of the measurement if the maximum penetration depth is adapted to the roughness of the sample.The influence of Surface Roughness on Instrumented It shows that if the maximum penetration depth is higher than 20 times the roughness Ra,the surface can be considered as flat for such load.Finally,the force-penetration depth curves for the rough sample shown in Fig.6 confirm the better repeatability of the measurement if the maximum penetration depth is adapted to the roughness of the sample.Surface roughness (Ra) Surface hardness 41 - 45 HRC 41 Surface roughness (Ra) Surface hardness 41 - 45 HRC 41 - 47 HRC 60 - 64 HRC 51 - 59 HRC Surface roughness Ra Surface hardness 41#216; Surface roughness Ra Surface hardness 41lt; 10 mm Chrome layer hardness 850-1100 HV 1.5217 1.7218 1.4034 - 1.4112 - 1.4125 - 1
