... decreases in drilling forces and temperature. Additionally, increasing dilutant hardness decreased microfiltration flux, but this effect can be counteracted with the addition of a chelating agent. metalworking lubrication drilling hardness hardness testing water lubricants coolants filtration...

... using X-Ray diffraction line profile analysis and hardness test. It is revealed that the structure could be represented by the diffraction profile and further by a parameter, Gaussian Curve Parameter (GCP), from fitting the diffraction line peak by a Gaussian curve. The thermal effect on structure can...
