Abstract:

The increasing use of 3D-printed PEEK materials in load-bearing applications necessitates a comprehensive evaluation of their wear characteristics and hardness under dynamic loading conditions. This study investigates the wear loss, coefficient of friction, and hardness values of PEEK materials with four distinct surface patterns: Line, Grid, Cubic, and Hexagon. Controlled experiments revealed that the Line and Hexagon patterns exhibited the lowest wear loss (0.004 grams), indicating superior wear resistance, while the Cubic pattern showed the highest wear loss (0.009 grams).

Abstract:

The determination of actual stresses over the tool-workpiece interface has long been a matter of debate among researchers. Evaluation of the nature and the geometry of the wear contact area were always associated with many, sometime impractical, assumptions. The indeterministic fashion of edge wear and deformation requires a more realistic way to predict the actual wear contact area. In the current study, many wear area patterns are proposed considering the different wear modes of the cutting edge. The selection of the most correlated pattern to a specific edge deformation is justified using t

This study explores the mechanisms underlying the enhanced anti-wear and thermal fatigue performance of laser-treated bionic brake drums, aiming to extend their service life and improve design quality. Bionic brake drums treated with laser patterns—point, stripe, and grid—were tested with semi-metallic, non-asbestos organic (NAO), and ceramic brake pads. A mechanical model was developed to analyze wear performance, and bench tests were conducted to assess wear patterns. Thermal fatigue tests examined the impact of thermal cycling on the treated drums’ wear behavior. The results reveal that las

ABSTRACT Tire wear performance is very important in terms of safety and economic benefit for customers and environmental conservation. Tire wear performance can be sorted into “global” or “local” wear. Local wear means uneven tire wear, for example, heel/toe wear, one-sided shoulder wear, feather edge wear, etc. This uneven wear decreases tire life locally and has the potential for causing a noise problem, so it is very important to improve uneven wear performance for long life tire. It is difficult to correctly evaluate the uneven tire wear performance of a brand-new tire, because the tire we

Comparisons of bulk flow and wear behavior between the convex pattern and flat surfaces illustrate the two-sided effect of the convex pattern surface on sliding wear.

AbstractMotor vehicle end-users approaches to tyre safety issues in automobiles translate to a number of tyre failure risk factors. This study basically assessed tread wear pattern of tyres in passenger cars used on Nigeria roads. The result obtained showed that 75.4% of the assessed tyres showed uneven wear pattern resulting from incorrect tyre-road contact effects. This observed high proportion of uneven tyre tread wear pattern implies high rate of inconsequential regard for tyre safety.

Abstract:

In this paper, based on micro wear form, an approach that using protrusion height, average tool angle, blunt area ratio and coated density to describe the wear of abrasive belt is put forward. The method for calculating the above parameters are also introduced. In experiments, we use the profilometer to collect the abrasive belt surface data and draw figures of the above parameters under service time, which indicates that using topography parameters can describe the degree of belt wear. According to parameters changing slope, the abrasive belt service time is roughly divided into two stages, i

Abstract:

In ductile metals, sliding contact induces plastic deformation resulting in subsurfaces, the mechanical properties of which are different from those of the bulk. This article describes a novel combination of nanomechanical test methods and analysis techniques to evaluate the mechanical behavior of the subsurfaces generated underneath a wear surface. In this methodology, nanoscratch techniques were first used to generate wear patterns as a function of load and number of cycles using a Hysitron TriboIndenter. Measurements were made on a (001) single crystal plane along two crystallographic direc

Abstract:

An experimental set-up and a procedure to make in situ localized measurements of various wear processes on magnetic thin-film disks are developed. The coefficient of friction, acoustic emission and optical reflectance are monitored simultaneously. Results are analysed to determine ‘precursors to failure’ and to compare the effects of lubricant, surface roughness, overcoat and normal load on disk wear. Disk wear is observed to follow a pattern of lubricant depletion followed by head slider-overcoat asperity contact. Wear tracks are formed after asperity contact. Lubricant extends disk wear life

Abstract:

A method of tool wear intelligence measure based on Discrete Hidden Markov Models (DHMM) is proposed to monitor tool wear and to predict tool failure. FFT features are first extracted from the vibration signal and cutting force in cutting process, and then FFT vectors are presorted and converted into integers by SOM. Finally, these codes are introduced to DHMM for machine learning and 3 models for different tool wear stage are built up. Pattern of HMM is recognised by calculating probability. The results of tool wear intelligence measure and pattern recognition of tool wear experiments show th

The polishing pad plays a significant role in the Chemical Mechanical Polishing (CMP) process and its wear influences the surface accuracy of the polished wafer. A new polishing pad wear model is introduced and the law of pad wear along the pad radius is discussed, thus a new FAP with optimized pattern is designed and prepared in order. The flatness of the wafer lapped with a uniform pattern pad and that with an optimized pattern was compared. Results show that the PV value of the latter is lower that of the former.
