Abstract

fetched live from OpenAlex

In this paper, an attempt was made to evaluate the tribological aspects of Al 6082 under lubricated conditions. The bio-lubricant jatropha oil was used, and its performance was compared with SAE20W40 engine oil. For enhancing the lubricating properties of jatropha oil, TiO 2 nanoparticles were used. Experiments were conducted with pure jatropha oil with different weight percentages of TiO 2 nanoparticles, such as 0%, 0.1%, 0.3%, and 0.5%. The coefficient of friction and specific wear rate of the Al specimens were determined using a pin-on-disc tribo-meter as per ASTM G99 standards, at a constant speed of 1 m/s and different loads, such as 20, 40, and 60 N. The experimental results indicated that the addition of TiO 2 to jatropha oil reduced the friction and enhanced anti-wear properties, compared with SAE20W40 engine oil. The lubricant viscosity and thermal conductivity were measured using a Redwood viscometer and a transient hot wire method. Surface analysis was performed using a scanning electron microscopy to study the surface morphology of the worn-out pin material. Surface examination revealed that TiO 2 nanoparticles lead to a smoother worn surfaces than commercial engine oil SAE20W40.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
