Effect of pretreatment by shotblasting prior to lubrication for cold forging
نویسندگان
چکیده
Effect of pretreatment by shotblasting to workpieces before lubricating a non-chemical conversion lubricant in cold forging was examined making several surfaces with different topographies, using wet shotblasting. Backward-cup extrusion test estimated the performance pretreatment. This provides extremely large surface expansion bring severe tribological conditions. After tests, insides cup-like were observed scanning electron microscope and surface-analyzed energy dispersive X-ray spectroscopy measure distributive amount on workpiece. The pretreated resulting aspect ratio (Ra / RSm) raised potential lubrication performance. Especially, treated angular shaped media indicated higher improve anti-galling

Effect of Ultrasound Pretreatment on Wood Prior to Vacuum Drying♠
The influence of ultrasonic pretreatment prior to vacuum drying of Chinese fir specimens was examined in this work. In the pretreatments, wood samples were immerged in a distilled water bath and were treated using two wave frequencies for four different elapsed times to investigate effects of ultrasonic frequency and treatment duration. Then the wood samples were vacuum-dried at 80°C and absolu...
متن کاملThe Effect of Gentle Exercise Prior to a Cold
A cold sensitivity test (CST) is one of the assessments used to classify the level of non-freezing cold injury (NFCI) in patients presented to a cold injury clinic. The CST involves sitting in a chamber at 30°C for at least 30 min then immersing the injured site (usually a foot) in water at 15°C for 2 min. The NFCI classification is based on the skin temperature before and 5 min after immersion...

Prediction of Residual Stresses for a Hollow Product in Cold Radial Forging Process
Radial forging is an open die forging process used for reducing the diameters of shafts, tubes, stepped shafts and axles and also for creating internal profiles such as rifling the gun barrels. The radial forging of tube is usually performed over a mandrel to create an internal profile and/or size the internal diameter. Most of the previous studies conducted on the radial forging process have u...
