Tribological Aspects of Slide Friction Diamond Burnishing Process

Area of Science:

• Materials Science and Engineering
• Surface Engineering
• Tribology

Background:

• Diamond burnishing is a cost-effective, low-environmental impact finishing process.
• Surface quality significantly influences tribological characteristics.
• 3D roughness parameters are crucial for assessing machined surfaces.

Purpose of the Study:

• To investigate the 3D roughness parameters of X5CrNi18-10 stainless steel after diamond burnishing.
• To evaluate the tribological characteristics influenced by surface quality improvements.
• To identify optimal process parameters for enhanced surface finish.

Main Methods:

• Analysis of surface layer condition using Abbott-Firestone curves.
• Measurement and evaluation of 3D roughness parameters (Sa, Sq, Sz, ISa, ISq, ISz).
• Experimental determination of optimal diamond burnishing parameters (speed, feed, force).

Main Results:

• Diamond burnishing significantly improved surface quality parameters.
• The best improvement ratios for Sa, Sq, Sz, ISa, ISq, and ISz were achieved.
• Optimal parameter combination identified: speed (v2) = 55.578 m/min, feed (f2) = 0.050 mm/rev, and force (F4) = 50 N.

Conclusions:

• Diamond burnishing effectively enhances surface topography and tribological properties.
• Specific process parameters are critical for maximizing roughness improvements.
• This study provides valuable insights for optimizing diamond burnishing in manufacturing.
