The quality of metallic additive manufacturing outputs is heavily dependent on the employed processing parameters. Hence, assessment and definition input variables appropriate to material in question vital importance, order optimise attainable properties minimise wasted feed stock failed trials. In this work, optimal parameters for 18Ni300 Maraging steel are found deposition an H13 substrate. A...

plasma electrolytic oxidation (peo) is the new, environmentally and cost-effective method for coating the metals. this method vastly has been studied for coating aluminum, titanium and magnesium and their alloys and recently for steel. in present study, ck45 steel samples were coated by peo method in order to improve corrosion resistance. during this process specimens were immerged in carbonate...

In this paper, low cycle fatigue life of CK45 steel and SS316 stainless steel under strain-controlled loading are experimentally investigated. In addition, the impact of mean strain and strain amplitude on the fatigue life and cyclic behavior of the materials are studied. Furthermore, it is attempted to predict fatigue life using energy and SWT damage parameters. The experimental results demons...

the plain carbon steel “ck45” has relatively well mechanical and metallurgical properties and low cost. the purpose of this research was the property evaluation of this steel on abrasive wear and impact for using in plows and other tillage tools. tillage tool should resist in abrasive wear and impact simultaneously. several heat treatments were done on specimens of this steel. a standard test d...

the effect of an electroless ni-cu-p coating on the fatigue behavior of quenched and tempered ck45 steel has been investigated. the fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. the results indicate that plating of the base steel leads to a fatigue life reduction. the d...

Obtaining the required surface finish and geometric accuracy together with attaining high production rate is a challenge in finishing of inner surfaces steel pipes bushes. One promising techniques for metal parts electrochemical machining. In this paper, roughness dimensional inaccuracy CK45 bush were controlled electrochemically. For this, special machine was constructed. The effect electric p...

Adding nanomaterials to quenching media is an innovative method alter alloys' mechanical properties and enhance their resistance wear. In this work, TiO2 nanoparticles were added the oil as a in different mass percentages (0, 0.2, 0.4, 0.6%) identify impact of adding on wear (dry sliding) by microstructure analysis carbon steel CK45 before after addition nanofluid. The results reveal critical r...
