Tensile behavior of gray cast iron with directional graphite flakes

This pure α-Al2O3 coating were used to high speed cutting of gray cast iron in our study,for solving the problem that κ-Al2O3 coating or κ-Al2O3 and α-Al2O3 coating couldn't be applicative stably in high speed cutting.

8%SiC)suggested by multi-factor regression analysis,the wear resistance layers on the surface of HT200 gray cast iron of about 3mm depth is obtained,and its wear resistance is 2.

The study of behavior of graphite phase in the laser hardening layer of gray iron;

In order to find a quick and accurate test method for discriminating the nodular iron from the gray iron on the production spot, ultrasonic attenuation tests were conducted on both the nodular iron and gray iron specimens with different thicknesses by adopting the ultrasonic waves with different frequencies.

Through the single factor test on gray iron added with Cr、Al、Cu respectively,the effect of the three elements on the cast structure and corrosion resistance has been analyzed.

The microhardness of nodular cast iron and grey cast iron treated by the technology of low temperature gas multicomponent permeation was studied.

The NiCrBSi powder alloying on the surface of grey cast iron was realized successfully by means of light beam heating.

The cavitation erosion behavior of TiN, CrN and (Ti,Cr)N hard coatings produced by arc ion plating on the surface of grey cast iron was studied with an ultrasonic cavitation erosion testing apparatus and a scanning electron microscope.

Influences of Technological Parameters on As-Cast Bainite Grey Iron;

A measuring method taking views of hydrogen behaviours under microscope is applied to study the redistributive and bubbling-up course of the residual diffusible hydrogen in the grey iron weldments welded with both the homogenous and the heterogenous electrodes.
