“…Many studies in the literature discussed the effect of various reinforcements over the base matrix of different Al alloy matrices. 41,42,43,44 They have highlighted the significance of FSP in improving the mechanical, rheological, and tribological behaviors of the prepared hybrid surface composites. Results of those studies have provided sufficient information on the utilization of V TRS , V TS , NoP, and RV as processing variables, which have the maximum impact on prepared surface composite.…”

Aluminum alloys are known for their extensive use in aerospace, automobile, marine, etc., industries due to their excellent inherent properties. Recent studies have developed different methods to modify the surface properties of aluminum by producing surface composites, such as the friction stir processing (FSP) method. The current study made an effort to develop a new hybrid surface composite of AA5083/(SiC-Gr) using the FSP method. For FSP process optimization, the response surface methodology (RSM) has been used. For creating the mathematical model using RSM, various input process parameters of the FSP are selected to predict the output characteristics of the prepared hybrid composite. A Box–Behnken design was used for the process with four factors, each factor was used with three levels, and the RSM was utilized to form a regression model to predict the responses. The ANOVA analysis suggests that NoP (number of passes): 3 and RV (reinforcement volume): 75:25 (SiC: Gr) ratio are the significant parameters of the study with a p-value less than .05. The novelty of this study lies in the development of a new hybrid surface composite of AA5083/(SiC-Gr) using the friction stir processing (FSP) method, with optimization achieved through the response surface methodology (RSM) and multi-objective selection criteria, resulting in predicted outcomes within a range of ±10% of the experimental observations.

“…Yigezu et al (2013) developed an insitu Al-12%Si/TiC composite and reported that the normal load was the dominant factor for material loss, and sliding distance was a major factor influencing the coefficient of friction (COF). Nathan et al (2023) developed AA7075graphene oxide-reinforced composites fabricated through the FSW method. The study shows a significant reduction in the coefficient of thermal expansion (CTE), hardness enhances the wear resistance, and the surface morphology of the worn surface reveals a mild adhesive with abrasive behaviour.…”

High-strength-to-weight ratio materials are crucial for the automotive and aerospace sectors, driving the demand for advanced solutions. Traditional monolithic materials fall short of meeting these requirements, prompting the exploration of ceramic-based metal matrix composites. Among these, the Al/B4C composite stands out for its exceptional wear-resistant properties, attributed to its heightened hardness and shear resistance. This study investigates the wear performance of AA 7050-7.5% B4C-T6 Composite, produced via flux (K2TiF6) assisted stir casting method. The wear rate serves as the primary performance metric, evaluated using a pin-on-disc tribometer. Experimental design employs a Taguchi L9 orthogonal array, facilitating systematic analysis. Taguchi Analysis optimizes the process parameters, revealing insights into their impact on wear performance. The wear rate directly correlates with both applied load and sliding distance, indicating higher wear with increased stress and sliding duration. Additionally, the sliding speed intermittently influences the wear rate due to a Mechanical Mix Layer (MML) presence, highlighting the complex interplay of factors influencing wear behaviour. In summary, this research underscores the potential of AA 7050-7.5% B4C-T6 Composite as a promising wear-resistant material, offering valuable insights into optimizing its performance through controlled process parameters.

“…One of the cutting-edge approaches is friction stir processing (FSP), which has the potential to alter the microstructural behavior of aluminum composites without compromising the mechanical characteristics of the basic substrate. [8][9][10] It also has the advantage of preventing the agglomeration of particles by uniform reinforcement distribution on the base matrix. 11 In FSP, a non-consumable tool including a shoulder that is moved towards the workpiece till the bottom face of the shoulder is in touch with the workpiece surface and the pin is plunged into the workpiece.…”

In this work, friction stir processing (FSP) was used to successfully embed boron carbide (B4C) particles into an aluminum matrix (AA6061-T6). Four specimens of aluminum 6061 composite reinforced with 4%, 6%, 8%, and 10% volume fraction of B4C were manufactured. The effects of B4C particles volume fraction on microstructure, mechanical and wear properties are investigated. The microstructural investigations demonstrated that a rise in the volume % of reinforcement greatly decreased the matrix grain size. The manufactured AA6061-T6 loaded with B4C surface composites demonstrated homogeneous B4C particle dispersion, with no significant particle clustering in the stir zone. In addition, it was established that increasing the volume fraction of B4C particles promoted grain refinement, increased hardness, and tensile strength. X-ray diffraction (XRD) was used to identify the reinforcement dispersion. For AA6061-T6 with 10% B4C particles, a maximum hardness value of 163 HV was obtained in the stir zone. Maximum yield strength of 165 MPa and ultimate tensile strength of 220 MPa were attained by AA6061-T6 with 10% B4C particles, which is an improvement of 21% over the specimen FSP without reinforcement. The strengthening of the grain refining was attributed for the increase in hardness and strength. The ductility was reduced by the incorporation of more B4C particles. Comparing the surface composite loaded with B4C to unreinforced friction stir processing and AA6061-T6 as received, it demonstrated superior wear resistance.
