Cutting Performance of Low Stress Thick TiAlN PVD Coatings during Machining of Compacted Graphite Cast Iron (CGI) [PDF]

Coatings, 2018
A new family of physical vapor deposited (PVD) coatings is presented in this paper. These coatings are deposited by a superfine cathode (SFC) using the arc method. They combine a smooth surface, high hardness, and low residual stresses. This allows the production of PVD coatings as thick as 15 µm.

Microstructure and properties of silicon alloyed compacted graphite irons (CGI)

Metalurgija, 2020
The microstructure, tensile properties and hardness of 25 mm thick compacted graphite iron samples alloyed with 3, 01, 3, 22, 3, 61, 3, 97 and 4, 29 wt. % Si were analyzed in this paper. It was found that Si promotes and strengthens ferrite. Metallic matrix of compacted graphite iron sample alloyed with 3, 01 wt. % Si consisted of 98, 1 % ferrite and 1,

Computational Assessment of Thermal Conductivity of Compacted Graphite Cast Iron

Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
Two‐dimensional FE models of CGI with different pearlite contents for thermal conductivity analysis were established according to the real metallographic images obtained by Pro/E and ANSYS. Meanwhile, thermal conductivity of CGI with different pearlite contents was tested through the laser flash method.

Processing Window and Microstructure of NiCoCrAlY Coating Deposited on Cast Iron Using Multilayer Laser Cladding

Journal of Spectroscopy, Volume 2019, Issue 1, 2019., 2019
Cast iron is an iron‐carbon alloy widely used in mechanical engineering. Nickel‐base or cobalt‐base alloy coatings prepared by laser cladding can improve the surface properties of cast iron, thereby increasing the service life of the components; however, due to the poor weldability and high carbon content of cast iron, the use of laser cladding to ...
