stainless steel natural gas grill Experimental and theoretical study on the driving force and glass flow by laser-induced metal sphere migration in glass

Light can move matter remotely.In a variety of driving forces, laserThe migration of metal balls induced in glass was reported.Temperature on the laser-The lighting side of the sphere is higher than the non-lighting sideLighting side.This temperature gradient leads to non-The uniformity of the interface tension between glass and molten metal decreases with the increase of temperature.In this study, we studiedConsidering the temperature dependence of material parameters, the metal ball migration is induced in different glass using heat flow calculation.In addition, the glass flow rate generated by metal ball migration is measured and compared with the thermal flow calculation.With the increase of laser power density, the migration speed of stainless steel sphere increases;The maximum speed in boron silicon glass is 104 μm/s, and the maximum speed in quartz glass is 47 μm/s.The ball is heated to multiple k.The temperature gradient of the interface tension between the stainless steel sphere and the glass is calculated as-2.29 × 10-5 n/m/K for boron silicon glass and 2.06 u2009 × 10-5 n/m/K of quartz glass.The glass flows through an area of 15-30 μm from the surface of the sphere, 80-The μm sphere migrated in a narrow softening channel.The experimental settings are shown.The configuration is the same as previously described.Stacking glass plates and stainless steel foil in the following order: 10-mm-Thick quartz glass (AQ series, AGC Asahi Glass Co., Ltd), Ltd.Tokyo, Japan), 5-mm-Thick boron silicon glass (Corning, Corning 7440)Corning, New York, USA), 10-μm-Thick stainless steel foil (SUS 304, #753173) and glass plate of niarko, Tokyo, Japan, to ensure good contact.Continuous wave fiber laser (RFL-Wuhan Ruike Fiber Laser Technology Co., Ltd. c20/A/2/, Ltd.Hubei, China) uses a wavelength of 1064 nm.M
