Effect of impact angle and impact velocity on the slurry erosion behavior of high density polyethylene (HDPE)‎

Abstract EN

High density polyethylene is widely used in many applications which deal withslurry because of its high erosion resistance characteristics.

Slurry erosion is a type of erosivewear which takes place when a stream of liquid hits a solid body and results erosion in thisbody surface.

Slurry erosion is affected by some parameters as material hardness, impactvelocity, impact angle, slurry content, ambient temperature, particle hardness, particle size andparticle shape.

The changing of these parameters individually will result in useful analysis forthe changing in slurry erosion rate with respect to the changed parameter.

This experimentalwork aims to investigate the slurry erosion behavior of high density polyethylene under theeffect of different impact velocities.

A slurry impingement test rig will be used to make thewear test and wear rate of HDPE is investigated as a function of impact velocity and impactangle.

Results showed that the maximum wear rate is at the lowest impact angle and maximumimpact velocity.

Weight loss is the indication of wear rate of the HDPE specimens afterexperiment and wear rate is defined as weight loss during the test time in [mg/h] unit
