“…Surface strengthening is crucial for enhancing the wear resistance of agricultural machinery. Agricultural machinery often operates in challenging conditions, and surface wear is a primary source of damage [71]. Surface-strengthening technology can substantially increase mechanical parts' surface hardness and wear resistance.…”

Agricultural mechanization is crucial in enhancing production efficiency, alleviating labor demands, reducing costs, improving agricultural product quality, and promoting sustainable development. However, wear and tear are inevitable when using agricultural machinery. The failure of critical wear-resistant parts is responsible for over 50% of rural machinery breakdowns. For instance, a domestic combine harvester typically only operates trouble-free for 20 to 30 h, and the service life of a rotary plow knife is approximately 80 h. Investigating the wear performance of key farm machinery components reinforces machinery design and maintenance strategies, extends machinery lifespans, enhances agricultural production efficiency, and advances agrarian sustainability. This paper provides a comprehensive overview of the latest research on the wear resistance of crucial agricultural machinery components. It delves into the factors influencing the wear resistance of these components and explores current effective measures to address wear-related issues. Additionally, it also summarizes the challenges and opportunities in researching the wear performance of key components in agricultural machinery and future development directions.

“…The energy consumption depends on the crop type, dry matter content, cutting length, and blades' sharpness [14]. The main variable cost of harvesting machines with other parts (ground speed belt drive, the shaft of the wheel and drive of grain elevator) is repair and maintenance due to cutting knife wear [15].The contact with different plants, stem diameter variations, moisture content variations, and stem hardness variations cause the cutting blades to wear [14,16]. The blade also ages due to stem aggregation around the cutting edge [17], cutting height [12], material surface and soil contact [18], impact wear, and intensive wear due to crash and scratch by by rocks and stems [19].…”

The productivity and efficiency of harvesting forage crops depend on the sharpness and quality of the mower blades. Therefore, studying blades wear during the harvesting process is crucial to sharpening and maintaining blades. The research aims to create mathematical models to predict the wear of mower blades and assess the wear rate of mower blades, fuel consumption, and CO2 emissions during harvesting operations. The wear of blades was measured and characterized by the weight loss method and scanning electron microscopy (SEM) before and after the field experiment. The results showed that the weight of the mower blade decreased from 103.82 to 98.39 g after 37.5 working hours. In addition, the wear of blades increased fuel consumption and operation cost with time. Also, CO2 emissions were 17.672 kg/h at the beginning of the experiment and increased to 29.516 kg/h after 37.5 working hours. From the obtained mathematical equations, the wear of the blade sharp part occurs after 34±3 work hours have passed, so the blades must be resharpened after this period.

“…A number of reinforcing particles were added into the nickel matrix to synthesise composite coatings with specific functions and applications. For instance, hard ceramic particles such as carbides [7,8], carbon nanotubes [9], oxides [10,11], borides [12], and nitrides [13] are selected as enhancing phases for MMCs to gain better mechanical and wear properties. Self-lubricating particles like graphene [14], sulphides [15,16], h-BN [17,18], etc.…”

Metal matrix composite coatings have attracted scientific and engineering interest because of their excellent mechanical properties. Nano-Si3N4 reinforced nickel coatings with different ceria contents were fabricated by electrodeposition. The microstructures, hardness, and tribological properties as well as corrosion behaviors of the composite coatings were studied in detailed. The results show that incorporation of ceria nanoparticles into the nickel matrix can decrease the grain size and facilitate the (111) texture of the coatings, leading to a smooth surface, compact microstructure, and dispersion-strengthening composites. The 6CeO2 coating with the highest hardness of 520 HV50g demonstrates the best wear resistance, while the 3CeO2 coating shows the best corrosion resistance with the smallest i corr value of 0.0972 μA/cm2. The study suggests a significant improvement in mechanical and anti-corrosion properties by incorporation with the ceria nanoparticles, which has important implications for the surface protection of engineering materials.
