Process-surface morphology-tribological property relationships for H62 brass employing various manufacturing approaches

Tribology International, 2020
Abstract The cylinder/valve plate friction pairs were proven to be subjected to wear and failure in axial piston pumps. The synergy method of surface micro-texturing and wet micro-blasting was put forward to enhance the tribological performance of H62 brass/38CrMoAl conjunctions.

Enhanced tensile and bending yield strengths of 304 stainless steel and H62 brass by surface spinning strengthening

Materials Science and Engineering: A, 2019
Abstract In this work, the tensile and bending yield strengths of 304 stainless steel and H62 brass are effectively enhanced by surface spinning strengthening (3S) that can introduce a strengthening layer with gradient microstructure on the samples.

Experimental Study of Hot Extrusion Micro Gear of Brass H62

Advanced Materials Research, 2011
A new micro-forming method, combining a metal’s super-plastic behavior with hot extrudsion technology, has been developed for manufacturing micro-gear from brass H62. The micro-gear, which modulus m = 0.125mm, pressure angle α = 20°, number of teeth z = 6, tip diameter d = 1mm, was selected and its dies were designed with a better die approach angle ...

Fabrication of superhydrophobic surface with enhanced corrosion resistance on H62 brass substrate

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020
Abstract Corrosion protection of metals plays an important role in developing economy. Inspired by the lotus leaf in nature, superhydrophobic surfaces with excellent water-repellent properties has great potential to solve corrosion problem. Herein, superhydrophobic surfaces with improved anticorrosion performance were achieved on H62 brass.

Effects of Grain Refiner and Cooling Rate on Solidification Structure of H62 Brass

Advanced Materials Research, 2013
In this paper, effects of different grain refiners on solidification structure of H62 brass under different cooling rates were investigate by macro corrosion, SEM and EDX analyses. Results of experiments indicate that the columnar crystal zone of H62 brass is completely eliminated and the grain size is reduced remarkably by 0.01%B.

Effect of passive film on the galvanic corrosion of titanium alloy Ti60 coupled to copper alloy H62

Materials and Corrosion, 2019
Ti alloys exhibit high potential because of the compact passive film. However, the effect of passive film on galvanic corrosion is not clear. On the one hand, the great potential difference can accelerate the galvanic corrosion of other metals with low potential.

Dissimilar Welding of H62 Brass-316L Stainless Steel Using Continuous-Wave Nd:YAG Laser

Materials and Manufacturing Processes, 2014
Continuous-wave Nd:YAG laser welding of H62 brass and 316L stainless steel was studied using welded joints made with different overlap configurations. Optical and scanning electron microscopies, energy-dispersive X-ray spectroscopy, and microhardness testing were used to analyze the microstructures and mechanical properties of the joints.
