Test Study

Friction-type high-strength bolt connectors are widely used in steel structure. However there has only general description for connection plate surface treatment method in the current Chinese design standards. Some research tests have been designed for different connection plate surface treatment method, which include different painting thickness and different blasting method. The results show that different treatment method has different anti-sliding coefficient. The anti-sliding coefficient would decrease with the surface coating thickness increase. The anti-sliding coefficient would less than 0.50 which the Chinese design standard required when some surface treatment methods are used, such as using steel wire section or using mixture of steel wire section and steel shot to sand blasting. So procedure qualification test is necessary to guide processing in order to ensure the quality of the products. It has certain conference value for practical engineering.

Antibacterial Potential

During the last decades, researchers have been growing the interest in surface treatment with an antimicrobial agent. Silver nanoparticles (AgNPs) are widely used in biomedical fields due to their potent antimicrobial activity. So, in this study was investigated silver particles (isles) coated on titanium surface for dental and orthopedic application. Silver particles coating process on titanium surface were performed via sputtering that is a plasma-assisted deposition technique with and titanium without treatment was applied as comparing standard. Plasma treatment parameters were optimized so that the result was not a thin film of Ag but dispersed particles of Ag on the Ti-cp surface. The alloy surfaces were investigated using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). In order to investigate antibacterial potential Staphylococcus aureus and Escherichia coli have been used at Agar diffusion assay. The results were analyzed by analysis of variance (ANOVA) in order to verify significant difference antimicrobial activity between samples that have shown no difference between the surfaces studied treatments. For silver deposition scattered particles (isles) over titanium surface for a 10-minute treatment, EDS revealed by silver clusters that the particles were not properly scattered onto surface, hence, the low effectiveness in antibacterial activity.
