“…Till now the samples for tests were cut from the cylindrical part of the tester using cut-off machine, but this method generated difficulties because of chromium cast irons high wear resistance [6][7][8][9][10][11][12]. Therefore, rose a concept to use the overflow part of ATD -C tester for casting easy to obtain samples for testing the abrasion resistance and mechanical properties.…”

The aim of presented studies was to develop a new geometry of the overflow part of standard ATD-C tester for derivative thermal analysis in a way that it would allow to obtain samples for abrasion and mechanical properties tests in the same mould without the need of cutting them from a block of material. The pattern of new ATD-P tester has parts reflecting implemented samples. Computer simulations regarding initial verification of new tester were performed in NovaFlow software. Chromium cast iron melts were made for testing the sampler in real conditions and TDA analysis for casting material were conducted. The sandmix was prepared on silica sand matrix per the ALPHASET technology. This new solution greatly simplifies the preparations of materials difficult to machine.

“…The production of this element from one material results in obtaining identical properties throughout the entire volume of the cast. In case of joining two materials of different properties, it enables maintaining of contrary desired properties, such as in case of the cast core which is characterised with plasticity and capability to transfer dynamic loads, while the working part should be characterised with higher abrasive wear resistance [6][7][8][9][10][11][12][13][14].…”

The paper presents a proprietary method of making composite cast iron (eutectic) locally reinforced with ceramics. The research included making casts with a ceramic layer, its percentage of the surface was 30%. The research included abrasive wear resistance according to ASTM G 65-00. As a result of the research it has been found that the infiltration of the molten metal into the ceramic preform mainly affects the correct production of the cast with local reinforcement. The research results also have proven that the application of a lattice ceramic insert placed in the mould is the most appropriate option, due to the even distribution of the particles in the cast and obtaining a sound cast.

“…In the last decade much emphasis has been placed on the enhancement of surface properties of the cast iron, such as its wear and corrosion resistance [1][2][3]. The most of reported works have been focused on laser surface modification methods of the cast iron, mainly laser surface melting (LSM) and alloying (LSA) processes [4][5][6].…”

Diode laser surface alloying process was used to the in-situ synthesis of TiC-reinforced composite surface layers on the ductile cast iron substrate. The obtained composite surface layers were investigated using optical and scanning electron microscopy, and XRD diffraction.It was found that the morphology and fraction of TiC phase is directly dependent upon both the concentration of titanium in the molten pool and also the solidification rate. With increasing titanium content, the fraction of TiC increases, whereas the fraction of cementite decreases. The TiC phase promotes a heterogeneous nucleation of primary austenite grains, what reduces a tendency of cracking in the alloyed layers.
