“…They are characterized by high wear resistance due to the presence, in their structure, of significant volume fractions (VF) of hard phases -carbides, nitrides, borides etc. [19][20][21]. As a rule, these alloys are subjected to bulk heat treatment (HT) in order to increase their hardness and wear performance [22,23].…”

Pulsed plasma treatment was applied for surface modification and laminated coating deposition on 14.5wt%-Cr cast iron. The scopes of the research were: (a) to obtain a microstructure gradient, (b) to study the relationship between cathode material and coating layer microstructure/hardness, and (c) to improve coating quality by applying post-deposition heat treatment. An electrothermal axial plasma accelerator with a gas-dynamic working regime was used as plasma source (4.0 kV, 10 kA). The layered structure was obtained by alternation of the cathode material (T1-18 wt% W high speed steel and 28 wt% Cr-cast iron).

“…A given technique is not due to cavitation factors; however, the results obtained are comparable to other studies into the cavitation process. In particular, we compared results from erosion tests obtained using three techniques: 1 -impact, applying the energy of a water jet periodically crossing the test sample; 2 -vibrational method, using a magnetostrictive vibrator; 3 -employing a hydrodynamic tube [1]. As a result of comparison, it was established that different testing methods provide indicators of the intensity of cavitation erosion, which differed insignificantly from each other.…”

“…However, some other investigators regard this alloy should be called graphite steel [11] . It has been reported that spheroidal carbide can further improve wear resistance and not reduce the impact toughness of the ductile irons [12][13][14] . However, little information is available in the literature on the carbide of the ultra-low carbon ductile iron, and the spheroidal carbide in the ultra-low carbon ductile iron has not been reported.…”

Male, born in 1957, Ph.D., Professor. His research interests mainly focus on the new type of abrasive materials such as ADI, CADI and their forming technology, the development of the iron melt quality online measurement and control system. A ustempered ductile iron (ADI) as a kind of very promising engineering material, is extensively used in gears, heavy machinery and transportation industries due to the combination of superior properties, such as high strength with good ductility, good wear resistance and fatigue tolerance [1][2][3][4] . The microstructure of the ADI consists of a certain number of graphite nodules, and the coarse graphite nodules with a strong fragmentation effect on the matrix structures seriously damage the properties of the materials [5,6] . Therefore, people try to obtain tiny, round and uniformly distributed graphite nodules to improve the mechanical properties by reducing the carbon content, and extensive efforts have been devoted to investigating ultra-low carbon ADI [7] .The ultra-low carbon ADI can be prepared with a certain composition of ductile iron through austempering heat treatment [8] , so an important step in the development of the ultra-low carbon ADI involves melting and casting of ultra-low carbon ductile irons. In the traditional Fe-C binary phase diagram, the right to the point (2.1wt.%) is called iron, and the left is called steel. However, the Abstract: The formation mechanism of the spheroidal carbide in the ultra-low carbon ductile cast iron fabricated by the metal mold casting technique was systematically investigated. The results demonstrated that the spheroidal carbide belonged to eutectic carbide and crystallized in the isolated eutectic liquid phase area. The formation process of the spheroidal carbide was related to the contact and the intersection between the primary dendrite and the secondary dendrite of austenite. The oxides of magnesium, rare earths and other elements can act as heterogeneous nucleation sites for the spheroidal carbide. It was also found that the amount of the spheroidal carbide would increase with an increase in carbon content. The cooling rate has an important influence on the spheroidal carbide under the same chemical composition condition.
