Effect Of Surface

The aim of the study is to investigate and to prove that the fatigue failure of steel is initiated from the surface. Hence the preventif action of smoothening the surface that has been loaded by fatigue loading is very important. The specimen of AISI 1045 Steel is loaded by means of rotary bending fatigue. The fatigue loading will be interupted as the fatigue life reaching 50% of fatigue life and 75% of fatigue life. During the interuption the specimen will be grinded and polished, before tested completely until fatigue fracture occured. The fatigue life of each group of scpecimen based on the art of loading will be compared to the specimen tested by fatigue loading without interuption.The Miner rule is used to evaluated the test result. The influence of interuption and surface treatment is evaluated and analyzed. ABSTRAKTujuan penelitian ini adalah untuk menyelidiki dan membuktikan bahwa kegagalan kelelahan baja dimulai dari permukaan. Oleh karena itu tindakan pencegahan dengan memperhalus permukaan sangat penting untuk mencegah beban kelelahan baja. Spesimen dari AISI 1045 Steel dimuat dengan cara uji kelelahan lentur putar. Kelelahan pemuatan akan disela sebagai umur kelelahan mencapai 50% dari umur kelelahan dan 75% dari umur kelelahan. Selama gangguan lainnya yang spesimen akan digiling dan dipoles, sebelum diuji benar-benar sampai patah akibat kelelahan yang terjadi. Umur kelelahan dari setiap kelompok specimen diuji berdasarkan beban akan dibandingkan dengan spesimen oleh kelelahan bongkar tanpa aturan. The Miner rule digunakan untuk mengevaluasi hasil tes. Pengaruh gangguan lainnya dan perlakuan permukaan dievaluasi dan dianalisis.

1045 Steel

Some mechanical properties of AISI 1045 borided steels were estimated in the present work. The boriding process was carried out by the powder pack method at 950°C with 8 h of treatment. The fatigue strength on borided notched specimens was evaluated with rotating bending tests (R=1) considering a stress concentration factor (Kt) of 2.53. Likewise, the presence of residual stresses in boride layers was established by the XRD technique. The Daimler-Benz Rockwell C test was used, also, to estimate the strength adhesion of the coated system. The results show a decrease in the fatigue strength of AISI borided steels due to the presence of high porosity in the layers. Finally, the Rockwell-C adhesion test showed no coating failure for the boride layer.

Main Material

AISI 1045 steel is a steel classified as medium carbon alloy steel which is widely used as the main material in machinery so it must have good mechanical properties such as hardness, wear resistance. The purpose of this study was to determine the effect of heat treatment on the wear rate of AISI 1045 steel. The research method used was AISI 1045 steel which was given a hardening heat treatment with a temperature variation of 800ºC, 850ºC, 900ºC with a holding time of 60 minutes, followed by rapid cooling using water . after that the specimen will be tested for wear by using a standard Pin On Disc. the results of the study show that the wear value at 800ºC has an average wear value of 15.0762 mg / cm², then at a temperature of 850ºC has an average wear value of 11.33933 mg / cm² and at a temperature of 900ºC has an average wear value of 9 9488 mg / cm². In conclusion, there was a very strong influence on the use of hardening temperature variations on the AISI 1045 steel wear and the smallest wear value on the specimen given by the hardening process at 900ºC with an average wear value of 9.9488 mg / cm².

Surface Heat Treatments

AISI 1045 steel is a steel of medium carbon, widely used in machinery, the automotive industry, and the food industry, among others. Therefore, to fulfill its purpose, it is necessary to improve its mechanical resistance, wear resistance and resistance to fatigue through different surface heat treatments. Variables such as heating time and hence speed affect the thickness of the hardened layer and the microstructural characteristics of the area affected by heat treatment. The inspection of the transformation of phases during the treatment and the thickness of the boundary layer is generated by determining the hardness of the material, whose procedure is subject to the ASTM E92-17 and E384-17standards, which establish the methodology to be followed. Therefore, the objective of this work is to quantify the effect of three heating times at 1123 K on the hardening of AISI 1045 steel and the regularity of the hardened layer to ensure its functionality as a component subjected to friction, in addition to developing a table of equivalences between the Knoop (HK), Vickers (HK) and Rockwell C (HRC) hardness scales.

Plating Layer

Chromium plating is used widely in industry to enhance wear, abrasion resistance and to restore the dimensions of undersized parts. However, tensile residual stress always exists in chrome layer because of hydrogen embrittlement so it affect to mechanical properties of the chromium plating machine element, especially in fatigue strength. In this paper, effect of residual stress in chrome plating layer to fatigue strength was studied. The sample (AISI 1045 steel) was plated with 10 and 60 micrometers thicknesses and residual stress in chrome plating layer was determined by X-ray diffraction technique (Cu-Kα radiation). The results showed that chromium layer thicknesses go up, tensile residual stress decrease and microcrack density increase. Consequently, fatigue strength goes down when chromium layer thicknesses increase.
