The tribological performance of TiN,WC/C and DLC coatings measured by the four-ball test

An innovative approach to improving the wear resistance and load-carrying capacity of surfaces is by development of novel systems featuring coating treatment. Evaluation of the tribological performance of three physical vapor deposition (PVD) coatings, namely, TiN, WC/C, and DLC (diamond-like carbon), is necessary to determine their suitability as coatings for high-speed and heavy-duty power-transmitting gears. The uncoated and coated steel balls were subjected to four-ball tests under lubricated conditions. An optical microscope and a scanning electron microscope were used to observe wear scars, and energy-dispersive X-ray analysis was performed to determine the chemical compositions of the materials; these methods were also used to analyze the wear mechanisms. The wear performance of the three coatings was compared, and a four-ball method extreme pressure test was performed to determine the last nonseizure load of each tribo-pair. The WC/C and DLC coatings showed excellent tribological performance under high contact pressures and thermal loads, and the benefits of these coatings increased with decreasing performance of the lubricating medium. Therefore, WC/C and DLC coatings are suitable for application in high-speed and heavy-duty gears. Oxidation wear and peeling, fatigue pitting, and adhesive transfer are the main coating failure modes of the TiN, WC/C, and DLC coatings, respectively.     

Study on the correlation of lab assay and field test for fouling-release coatings

In this paper, two organisms, diatom and Ulva spore, were employed to evaluate the antifouling performance of five fouling-release (FR) coatings in laboratory, and field test was also assessed. The correlation of lab assay and field test was studied using Spearman's rank correlation test. The results show that the Spearman's coefficient (r_s) between lab assay and field static test is 0.975 (p = 0.005) for diatom and 0.949 (p = 0.014) for Ulva spore respectively, which are significant at the 95% probability level. This indicates that the lab static assays using diatom and Ulva spore have good agreement with field static test. For dynamic performance evaluation, the r_s between diatoms adhesion assay and field dynamic test is 0.894 (p = 0.041) while the r_s for Ulva spore is 0.289 (p = 0.638), indicating the lab dynamic assay with diatom is accordance with the field dynamic test. Therefore, diatom was used to evaluate the performance of coating materials which exhibits the satisfactory correlation and consistency between lab assessment and field test, confirming that diatom is an adapted evaluation organism to evaluate FR coatings.     

The influence of seasonal conditions,plant species and fertilizer type on the prediction of plant yield using the Colwell bicarbonate soil test for phosphate

Testing for soil phosphate (P) using the Colwell procedure is widely used in south-western Australia to estimate fertilizer applications required for crops and pastures. The relationship between plant yield, expressed as a percentage of the maximum yield, and soil test values is assumed to be constant in different years for the same soil type and plant species. Data from 11 long-term field experiments in south-western Australia show that regardless of whether percentage of maximum or absolute yield is used, the relationship between yield and soil test values is different (1)in different years, for the same site and where the same P fertilizer type has been used. This occurred irrespective of whether the same or different plant species were grown in different years; (2)where different types of P fertilizer had been used, for the same site, same year and same plant species; (3)for different plant species, for the same site, same year, and same type of P fertilizer. We conclude that considerable errors in the recommendation of fertilizer rates may result from the assumption that there is a constant relationship between soil test and yield.
