control of the wetting properties of an aisi 316l
Materials Science. Journal of Micromechanics and Microengineering. A simple and effective method without vacuum to control the wetting properties of AISI 316L stainless steel using femtosecond laser pulses at high repetition rate has been developed. Both hydrophilic and hydrophobic surfaces were formed by creating micro-conical structures on the surface with femtosecond laser irradiation in air.

Although AISI 316L has been intensively investigated as an AM material for powder bed fusion applications [6-11] and has been shown to show Table 1 Material properties reported for AISI 316L categorised by WAAM process type, specimen orientation and interpass build To control the material microstructure and properties developed Corrosion of Stainless steel 316 L with Time in Various The material used in this work is (AISI 316L) stainless steel, it is machined and formed to discs of (20) mm in diameter and (4) mm thick. Analysis of these surfaces, including the edges were wet ground using 120, 220, 320, 600, 800, 1000, and 1200 grit silicon carbide papers. These samples were then cleaned with water, and High density sintered stainless steelsPurpose:of this paper is the study of the properties of sintered AISI 316L (1.4404 according to EN 10088. Sintered stainless steels occupy a prominent position in the high alloyed steels, however their properties
Nov 08, 2019 · To understand the trends of the control parameters on R a of AISI 316L, the main effects analysis was carried out. As can be seen in Fig. 2, the smaller values of the R a are obtained under wet milling conditions, whereas dry machining conditions of AISI 316L produce higher R a values. This behavior is explained by the fact that the dry cutting conditions are responsible for generating a great Laser Nanopatterning for Wettability Applications J Mar 24, 2017 · Copper (99.9% purity), aluminum alloy, and stainless steel AISI 316L samples with a dimension of 20 × 20 × 5 mm were mechanically polished and cleaned in ethanol before testing. The initial roughness of the samples was evaluated by means of atomic force microscopy (AFM) analysis and the results are shown in Table 1 . Laser texturing of AISI 304 stainless steel:experimental Sep 18, 2020 · This paper deals with an experimental investigation of roughness influence on contact angle measurements and proposes a genetic algorithm to identify an empirical regression model to combine roughness and contact angles. A ns-pulsed laser was adopted to ablate different patterns on the surfaces of AISI 304 samples. During the tests, number of repetitions, hatch distance, laser scan
In addition to excellent corrosion resistance and strength properties, the Types 316, 316L, 317, and 317L Cr-Ni-Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steels. Specifications. Chemical Composition, % 18. Tribological Response of Mechanical Attrition Treated Aug 24, 2020 · Abstract. Current work focuses on studying the tribological response of the severely deformed surface of AISI 316L steel specimens using a ball-on-disk tribometer. Specimens are investigated under dry and lubricated (using engine-oil) conditions using different loads and sliding velocities. Surface mechanical attrition treatment (SMAT) using 6 mm diameter balls improves the Control of the wetting properties of an AISI 316L Aug 28, 2012 · Using low pulse energy (<10??J) and high repetition rate (? 500?kHz), AISI 316L SS surfaces were manipulated to control wettability which was demonstrated by a wide range of liquid contact angles. In addition to the fluence, the scan speed played a key role in controlling surface wettability by changing micro-cone number density (or the size of micro-cone microstructures).
