“…The Residual versus order plot of the hardness residual is in the order that the data was collected and can be used to find non-random error, especially of time-related effects [14,15]. The lack of pattern in this plot for the hardness response showed that the independence assumption is valid.…”

This work examined the optimization of hardness test for Powdered Pentaclethra macrophylla Pod /Bio-Epoxy Resin Based Brake Pad Composite Using Central Composite Design. The Pentaclethra macrophylla pod was manually cleaned and sun-dried for about three hours per day for three days. The sun-dried Pentaclethra macrophylla pod was later ovum dried at a temperature of about 110oC for three hours to achieve a constant weight and subsequently allowed to cool to room temperature. The ovum-dried Pentaclethra macrophylla pod was crushed to powder form using locally fabricated grinding machine and sieved. Part of the sieved powdered pod was carbonized in a heat treatment furnace at a temperature of about 950oC. Pre-impregnated process was used to prepare the brake pad composite samples. The weights of the powdered Pentaclethra macrophylla pods and bio-epoxy resin were varied while those of the lubricant, abrasives, friction modifier, catalyst and accelerator were kept constant The weights of the reinforcement i.e. powdered Pentaclethra macrophylla pods were varied between 10 wt. % and 50 wt. % at an interval of 10 wt. %. The formulation was poured into a wooden mould 50 mm × 50 mm × 8 mm placed in a hot platen press at temperature of about 180oC, a moulding pressure of 15MPa and a curing time of 5 minutes. Post-heat treatment of the composites was performed in a hot air oven for a period of 4 hours at 180 °C. The produced brake pads were evaluated for hardness in accordance to ASTM D785 standard using Rockwell Scale K hardness testing machine. The results of the test showed that 150μm particle size reinforced brake pad sample had higher hardness values of 105.7 and 106.4 at 20wt. % and 30wt. % respectively. This result was also confirmed by the Central composite design (CCD) where maximum hardness values of 107.31 and 107.63 were obtained at 20wt. % and 30wt. % respectively.

“…High-velocity oxy fuelsprayed materials such as chromium, silicon carbide, carbon monoxide, titanium dioxide, tungsten carbide, and aluminum oxide are used to improve wear and corrosion behaviour in industries such as printing and mining machinery, aircraft, automobile, shipping, and textiles. In contrast, wrought iron carbide is widely acknowledged as a hard ceramic material with superior mechanical, physical, and chemical properties that outperform all other ceramic materials [7][8][9][10][11].…”

The current work investigates the erosion-corrosion behaviour of thermally sprayed tungsten carbide-10% nickel (WC-10% Ni) coatings placed on the AA6061 aluminum alloy. The AA6061 aluminum alloy was coated with tungsten carbide –10% nickel coatings utilising a high-velocityoxy-fuel (HVOF) spray method. The microstructure and hardness of thermally sprayed coatings were examined using a scanning electron microscope (SEM) and a Vickers hardness tester. The slurry erosion-corrosion wear tests were carried out by varying the parameters of the slurry erosion process, such as testing time, slurry content, slurry speed, and impinging particle size, on the erosion testing equipment. The data demonstrated that when slurry concentration, slurry speed, and impinging particle size increased, so did the slurry erosion-corrosion wear loss. The wear processes of uncoated and thermally sprayed tungsten carbide –10% nickel have been examined using SEM and a 3-D confocal microscope.

“…Different surface treatments of equipment subject to wear can significantly increase the service life of tillage machines and reduce production costs. Researchers working on this topic [4][5][6][7][8][9][10][11][12][13][14][15][16][17] have improved surface performance by coating metal alloy powders using thermal spray technology. Thermal spray coatings are a well-developed and flexible surface engineering technique in which metallic and ceramic materials are sprayed onto the substrate surface in a molten or semi-molten state by kinetic energy [6].…”

The wear that occurs during tillage in agricultural machinery shortens the material’s life and increases costs. This study investigated the microstructure and morphology of cultivator blades coated with atmospheric plasma spray (APS) process and tested under real field conditions using OM, SEM, EDX, and XRD techniques. Abrasion tests were conducted in an area of 110 hectares and under two different soil moisture conditions. Material properties were investigated using hardness and surface roughness tests. The coating process was successful both mechanically and metallurgically by applying Ni-WC ceramic-metal (cermet) powder on the surface of 30MnB5 steel substrate with APS. The oxide and carbide structures detected on the coating surface by XRD studies resulted in a 1.5 times higher coating hardness. Due to the hard carbide phases in the coating matrix, the grooves on the wear surfaces were shallow and narrow compared to the substrate sample. The surface roughness values of the coated sample were approximately two times higher than the substrate sample. Due to the microstructure and high hardness, the coated specimen experienced three times less abrasion in both humidity conditions. The APS method can be successfully applied to the machined parts of tillage machines. In the near future, the cost of agricultural production can be reduced, and the environment can benefit from this method. In conclusion, this study presents a feasible approach to improving the wear resistance of Ni-WC ceramic-metal alloy by plasma spray coating under real field conditions.
