“…The influencing parameters on sliding wear rate and wear behaviour were reported in [5][6][7]. Hence, the present study was attempted to improve the dry sliding wear behaviour of Al 6061 alloy reinforced with TiB 2 at different loads and speeds.…”

The present paper deals with the study of microstructure and wear characteristics of TiB2 reinforced aluminium metal matrix composites (MMCs). Matrix alloys with 5, 10 and 15% of TiB2 were made using stir casting technique. Effect of sliding velocity on the wear behaviour and tribo-chemistry of the worn surfaces of both matrix and composites sliding against a EN24 steel disc has been investigated under dry conditions. A pin-on-disc wear testing machine was used to find the wear rate, in which EN24 steel disc was used as the counter face, loads of 10-60N in steps of 10N and speeds of 100, 200, 300, 400 and 500 rpm were employed. The results showed that the wear rate was increased with an increase in load and sliding speed for both the materials. However, a lower wear rate was obtained for MMCs when compared to the matrix alloys. The wear transition from slight to severe was presented at the critical applied loads. The transition loads for the MMCs were much higher than that of the matrix alloy. The transition loads were increased with increase in TiB2 and the same was decreased with the increase of sliding speeds. The SEM and EDS analyses were undertaken to demonstrate the effect of TiB2 particles on the wear mechanism for each conditions.

“…Various authors have researched the injection of WC in Ti6Al4V and found that the interaction between the molten metal and WCp is the key factor for obtaining a good distribution of particles and a controlled dissolution. 50 In this way, it is possible to produce a dense and well adhered layer of TiC around WC particles. 51 Another alternative is based on Ti-TiB 2 and offers toughness, mechanical strength, and resistance to creep.…”

This paper reviews progress over the last five years in the field of laser surface modification of titanium alloys. The authors analyze the effect of new laser technologies and new materials as tools for improving surface properties-specifically, biocompatibility and resistance to wear, corrosion, and high temperatures. The authors discuss the effect of laser processing parameters on the microstructure and compare the results obtained by various researchers. Therefore, an overview of the difficulties involved in the laser processing of titanium is provided with a discussion of future prospects.

“…Similarly, the test results from the wear measurements and model forecast for MI-IPCs were summarized in Table 1. Specific wear rate W C , which is the measure of removed volume per unit slide distance and unit load, was estimated by two different methods [21]. Firstly, W Cm was calculated from the mass loss of the specimen, determined by weighing the specimen before and after the test.…”

Owing to the brittle reinforced phase are introduced into ductile matrix phase, metal-intermetallic interpenetrating composites exhibit various types of wear mechanism such as adhesive, abrasive, and fatigue wear. In present work, the wear model has been proposed according to the mixing rule. Many factors such as special topology structure characteristic of reinforcement and elastic module were discussed in this model. The model based on the maximal and minimal hypothesis posts the mathematic relation among volume content of reinforcement, elastic module and wear rate. Increase in the volume fraction of reinforcement leads to improvement in the wear resistance. Unlike the Khruschov model and Zum-Gahr model, the proposed model was no longer follow linear rule. One kind of Al 3 Ti/Al composite with different volume content was fabricated and many wear test data were obtained to validate the correctness and universality of the model.
