“…The difference of Zn nucleation mechanisms can be attributed to the presence of GO in the ChCl : 2urea DES changing the thickness of electrical double layer and the surface charge of particles. 3 This shows that the (002) plane of Zn in the presence of GO have the lowest surface energy. 5.…”

In this work, novel zinc-graphene oxide (Zn-GO) composite coatings were successfully prepared by pulse electrodeposition in choline chloride (ChCl)/urea based deep eutectic solvent (DES). The GO sheets exhibited excellent dispersion stability in ChCl : 2urea DES without stabilizing additives and were uniformly deposited in the Zn matrix. The surface morphology and textured structure of the Zn-GO composite coatings were quite different from those of pure Zn coating, owing to the effects of GO on the electrochemical deposition behavior of Zn(II). The Zn-GO composite coatings showed higher stability and better corrosion resistance than the pure Zn coating and the corrosion resistance of Zn-GO composite coatings increased with the increase of the GO concentration.

“…Cerium oxide nanoparticle has many excellent properties, such as hardness [21,22] and corrosion resistance [23], and it is used in the laser treatment of alloys [24], electro-deposition [25], surface coating [26], etc. In studies that use rare earth elements to improve the performance of MAO coatings, researchers usually put the sample into the rare earth salt solution before the MAO process to obtain composite coatings [27].…”

This study evaluated the effect of an increase in carbon content and the presence of the elements Mo and V on the microstructure and properties of the surfacing layer of stainless steel powder for knives and scissors production. Various types of high-quality stainless steel powder (5Cr 13 , 8Cr 13 , and 8Cr 13 MoV) were deposited on the surface of low-grade stainless steel used to produce knives and scissors (2Cr 13 ). The microstructure, comprehensive hardness, wear resistance, impact toughness, and corrosion resistance of the stainless steel powder surfacing layers were tested and analyzed. Results indicate that the increase in carbon content and the presence of Mo and V improve the comprehensive hardness and wear resistance of the stainless steel powder surfacing layer, and both exert the superposition effect. However, the increase in carbon content and the presence of Mo and V slightly influence the impact toughness of the surfacing layer. In addition, the increase in carbon content significantly reduces the corrosion resistance of the surfacing layer. This adverse effect is reduced when Mo and V exist. Other advantages of the presence of Mo and V in the stainless steel powder surfacing layer include the refinement of grain size, reduction of carbide particle size, and improvement of the metallurgical bonding of the surfacing layer and the matrix.Coatings 2020, 10, 371 2 of 16 barber tools, which are seldom used in daily life. Therefore, to manufacture high-quality knives and scissors that can be used by the general public, this study explores a method to produce such instruments by plasma surfacing. The surfacing layer obtained by plasma surfacing can achieve large thickness [20,21]. This characteristic is used for surfacing powders of high-grade materials for knife and scissors production on the surface of massive low-grade materials for knife and scissors production. The composite material is then longitudinally cut. The thicker surfacing layer is directly used to produce the edge of knives and scissors, while the matrix (low-grade materials) is used to produce the body of knives and scissors. The method belongs to local strengthening of knives and scissors. The advantage of this method is that only the edge of a knife or scissors is mainly forced and abraded during use [22][23][24]; most high-grade materials are in an idle state of inaction. Limiting the use of high-grade materials to the production of the edge of a knife or scissors can not only meet the requirements for knife and scissors production but also reduce waste (of high-quality materials) and limit costs. However, no studies have been reported on surfacing high-quality stainless steel powder for knife and scissors production, and no methods have been developed to evaluate the microstructure and properties of the surfacing layer of high-quality stainless steel powder for such production.This study mainly aims to explore the microstructure and properties of the surfacing layer of high-quality stainless steel powder for knife and scissors product...
