Effect of heat treatment on wear resistance of high chromium white cast iron

The research included a study of the wear and hardness of the white high chromium cast iron, which will be used in the form of blocks for lining the rock mills in the Kufa cement plant.

Several heat parameters were used to alter the microstructure and improve the properties above. Scanning electron microscopy and optical microscopy were used to study the nature of the microscopic structure and x-ray diffraction to find out the phases formed before and after the thermal treatments.

The results showed that heat treatment at 1100 ° C followed by revision at 400 ° C produced the best anti-wear performance.

As for the second axis / medical materials engineering for the student Russell Ali Talib and under the supervision of Assis.Dr. Fatima Jaafar Mohammed

Evaluation Of Cytotoxicity And Cell Attachment For Titanium - Cobalt Alloy

The aim of the research is to find out the compatibility of titanium-cobalt alloys with the use of different percentages of cobalt with human-like cells (MG-63) and to study the effect of cobalt percentage on toxicity.

The sample was prepared and then subjected to various tests (X-ray diffraction, scanning electron microscopy (SEM), MTT examination (cell proliferation and adhesion took place two days after the transplantation, cell presence took place at 14,7,3 day intervals).

The X-Ray result showed that in the main sample one phase appeared, which is (a), but when we added Co, another phase appeared, which is the compound Ti2Co.

As a result of SEM, changes in the microstructure were clearly observed when we added 15% of CO.

The result of cell adhesion and presence showed an increase in the percentage of the compound when we added Co. This result showed us that Ti-Co alloy is useful, safe and non-toxic.

The third axis included / rubber technology for the student Waddah Mahmoud Ahmed and under the supervision of Prof. Shaima Mahdi Saleh

"Characterization of Reinforced NBR used for Fabrication of LPG Hoses"

The project aimed to improve the mechanical properties of the rubber used to manufacture LPG transport hoses in the oil sector with carbon fibers to develop a new material with good properties and a longer service life.

The rubber was prepared by means of kneading and vulcanization to increase the bond between the polymer chains and enhance the mechanical properties.

The hose designed to transport liquefied petroleum gas (LPG) from storage places to pelvic tankers consists of NBR rubber, which is a tube of the aforementioned rubber covered with another layer of chloroprene rubber separated with a layer of fibers, whether mineral or different fibers for the purpose of improving the mechanical properties of the rubber material to withstand conditions Harsh operating temperature, pressure and long operating hours.

The development of rubber compounds for these technical applications has been an ongoing challenge for researchers, as pressure and temperature in the oil and gas industry are gradually becoming more severe.
