主 题：Laser surface texturing Co-Cr-Mo alloy Surface roughness Wettability Bionic
摘 要：This study presents a comprehensive approach to applying texturing processes created by engraving on the surface of CoCr28Mo alloy workpieces using a 20 W pulsed nanosecond fiber *** hatch strategy and distance,frequency,and scan speed were control parameters for texturing *** effectiveness of the parameters in terms of roughness and contact angle of the texturized surface was *** roughness and contact angle were analyzed using variance analysis to identify each variable s *** has been determined that the roughness of the texture defined by the hatch strategy plays a decisive role in the wettability behavior of the surface;however,the scan speed,frequency,and hatch distance which are among the laser surface texturing conditions are influential in the roughness and contact *** scan speed and hatch distance while decreasing frequency resulted in smoother surfaces,increasing the contact *** having rough surfaces produced with different processing conditions exhibit a super hydrophilic *** contact angle is most sensitive to the hatch distance;however,the frequency has the least influence on the contact *** most and least efficient surface roughness parameters are revealed to be scan speed and hatch distance,respectively.
