Description

Archives of Foundry Engineering continues the publishing activity started by Foundry Commission of the Polish Academy of Sciences (PAN) in Katowice in 1978. The initiator of it was the first Chairman Professor Dr Eng. Wacław Sakwa – Corresponding Member of PAN, Honorary Doctor of Czestochowa University of Technology and Silesian University of Technology. This periodical first name was „Solidification of Metals and Alloys” , and made possible to publish the results of works achieved in the field of the Basic Problems Research Cooperation. The subject of publications was related to the title of the periodical and concerned widely understand problems of metals and alloys crystallization in a casting mold. In 1978-2000 the 44 issues have been published. Since 2001 the Foundry Commission has had patronage of the annually published “Archives of Foundry” and since 2007 quarterly published “Archives of Foundry Engineering”. Thematic scope includes scientific issues of foundry industry:

  • Theoretical Aspects of Casting Processes,
  • Innovative Foundry Technologies and Materials,
  • Foundry Processes Computer Aiding,
  • Mechanization, Automation and Robotics in Foundry,
  • Transport Systems in Foundry,
  • Castings Quality Management,
  • Environmental Protection.

Abstract

The resistance of cast iron to abrasive wear depends on the metal abrasive hardness ratio. For example, hardness of the structural

constituents of the cast iron metal matrix is lower than the hardness of ordinary silica sand. Also cementite, the basic component of

unalloyed white cast iron, has hardness lower than the hardness of silica. Some resistance to the abrasive effect of the aforementioned

silica sand can provide the chromium white cast iron containing in its structure a large amount of (Cr, Fe)7C3 carbides characterised by

hardness higher than the hardness of the silica sand in question. In the present study, it has been anticipated that the white cast iron

structure will be changed by changing the type of metal matrix and the type of carbides present in this matrix, which will greatly expand

the application area of castings under the harsh operating conditions of abrasive wear. Moreover, the study compares the results of

abrasive wear resistance tests performed on the examined types of cast iron. Tests of abrasive wear resistance were carried out on a Miller

machine. Samples of standard dimensions were exposed to abrasion in a double to-and-fro movement, sliding against the bottom of

a trough filled with an aqueous abrasive mixture containing SiC + distilled water. The obtained results of changes in the sample weight

were approximated with a power curve and shown further in the study.
