In the present work, three different scratch tests are compared on their ability to rank the abrasion resistance of low alloy steels for industrial applications where the abrasion play a key role, e.g., in earthmoving, agricultural and mining equipment. The first test involves single pass scratching of pristine surfaces with a relatively large rigid indenter. The second test involves multi-pass scratching...
In the literature many researchers have tried to correlate the (dry) abrasion resistance of steels to their standard mechanical properties as determined in simple tensile and hardness testing. However, many unclear or even conflicting correlations have been reported, in part due to small data sets being used, different testing methods and relatively simple data processing techniques. In the present...
An experimental investigation of the scratch and abrasive wear behaviour of a lean C–Mn construction steel in its tempered fully martensitic (TM) state is presented. The scratch resistance and the corresponding failure mechanisms as a function of the tempering temperature (200–500°C) were evaluated using a multi-pass dual-indenter (MPDI) scratch test applying different loading conditions. Results...
A systematic experimental investigation concerning the effect of ferrite–martensite morphology on the scratch and abrasion resistance of ferrite–martensite dual phase (DP) steels is reported. A hot rolled 22MnB5 steel was subjected to different heat treatments to generate dual phase microstructures with different ferrite–martensite morphologies. The effects of morphology on the scratch resistance...
A systematic experimental investigation was conducted to study the effect of the martensite volume fraction on the scratch and abrasion resistance of ferrite–martensite dual phase (DP) steels. Dual phase microstructures with relatively high martensite fractions were generated by tailored intercritical annealing treatments. The scratch resistance and corresponding failure mechanisms were evaluated...
Multi-pass dual-indenter (MPDI) scratch tests were carried out on a wide range of steels with different microstructures to investigate the relation between the formation of subsurface deformation layers under repetitive local sliding contact and their abrasion resistance. Five steel grades with different work hardening capability, i.e. Interstitial-Free steel, Fully Martensitic steel, Dual Phase steel,...
A proper understanding of abrasion resistance and associated damage mechanisms is of vital importance in the design of improved abrasion resistant construction steels. The conventional scratch test, sliding a rigid indenter under a controlled load and speed against a smooth surface, mimics the nature of the abrasion process and can be used to evaluate the abrasion resistance of various microstructures...
Abrasion resistant steels in combination with a good formability and a desirable balance of strength and ductility are in high demand for industrial applications. Current developments of high end abrasion resistant steels are mostly oriented on the high hardness martensitic concept following the hypothesis that the abrasion resistance holds a monotonous relationship with hardness. However, various...
The nano-scratch behavior of amorphous carbon films prepared on Ti alloy substrate by rf PECVD was evaluated using a nano indenter system with an attachment for lateral force measurement. The scratching processes were analyzed to understand the deformation behavior and the failure mechanism of the films. It was concluded that, three processes containing fully elastic recovery, asynchronous recovery,...
