3. Results and Discussion 3.1. Fatty Acids and Triacylglycerols of Red Palm OilsThe fatty acid compositions of each fat sample are presented in Table 1. The most abundant fatty acids in HRPO and NRPO were palmitic acid (C16:0, 34.95–42.96%), oleic acid (C18:1, 38.99–42.27%), and linoleic acid (C18:2, 10.70–11.57%); in addition, the fat contained appreciable quantities of stearic acid (C18:0, 3.87–5.83%). The total unsaturated fatty acids accounted for 49.69–54.40% of the fat.

The diamond grits pre-brazed using an amorphous nickel (Ni)-based alloy were accurately fixed onto some positions on a steel substrate by resistance spot welding with a hot-pressing function. The amorphous Ni-based alloy thoroughly wetted and wrapped the diamond grits in the pre-brazing process. After the resistance spot welding, the pre-brazed diamond grits and steel substrate formed a strong metallurgical bonding under resistance heat and electrode pressure.
