FINITE DIFFERENCE MODELING ON THE TEMPERATURE FIELD OF ALUMINIUM AND LOW CARBON STEEL IN FRICTION SURFACING

ABSTRACT
Friction surfacing is an emerging surface engineering technology, an advanced process of great potential, especially in the field of repair and reclamation of worn and damaged components. The temperature field of Mechtrode (consumable rod) in friction surfacing, as a kind of thermal processing technology, is an important factor in the successful implementation of the process. In this work, the temperature model of mechtrode in friction surfacing is established. Using finite element method the temperature field of consumable-rod during the friction surfacing process is simulated. In this work low carbon steel (EN1A) is used as …show more content…

Section of the consumable-rod at different rotational speed. Prior to the completion of friction preheating, in other words, at a time shorter than preheating time (e.g., 10, 20, and 30 s), the main heat source is generated through friction, and the temperature profile along the radial direction represents. Consequently, when the temperature at the friction interface becomes sufficiently high, the material completely transforms into plastic, the stress field has likely become uniformed, and friction heat increases rapidly at the outer areas, such that the temperature profile along the radial direction represents. In this work we give different rotational force to the mechtrode (900, 1000, 1100, 1200, 1300, 1400, and 1500) rpm. Table 3 shows the simulation values for different rotational speeds. The optimum result we can get from 1500 rpm of the mechtrode rotational

    The design relied on two Schmitt triggers to generate the two different tones while using the transistors to act as a switch. This causes it to trigger continuously between two unstable states, allowing automatic switching between two frequencies producing two different tones. The RC values between the two Schmitt triggers will differ. Capacitors charge and discharge faster when it’s resistance is smaller.

    Results The lab experiment was done in two parts, one with the NAND, NOR, XOR and Hex Inverters and the other with a 7483 full adder gate, both will verify the truth table when two input bits and a carry are added together. The circuits were built by examining the 1 bits through a K-Map to create a Boolean expression for the sum and carry. The Boolean expression for the sum was A⊕B⊕C and the carry as AB+BC_in+AC_in. From these two expressions, we notice that we must use two exclusive-ORs gates in the sum inputs for A, B, and C. For the sum, we have to use NOR and NAND (the only available gates from the lab manual).

    Experiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

    Identification of bacteria within Unknown Culture #21 In this experiment, an unknown culture of two different types of bacteria was assigned to each person, a number of tests were performed to isolate and identify these bacterial cells. Based on knowledge from the previous experiments completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test.

    Daphnia Magna are small crustaceans that are excellent for observing the effect of depressants on their nervous system. The purpose of this specific experiment is to observe the effect of ethanol, aspirin, and caffeine on daphnia’s heart rate. Not only do these chemicals affect heart rate, but they also affect the frequency of reproduction, number of eggs produced, and body structure. Pesticides similar to these chemicals can be released into the environment and daphnia re useful in monitoring toxicity levels. The agents being tested in this experiment can be administered to determine the effects of hormones, stimulants, antidepressants, and neurotransmitters.

    This question requires knowing the Beadle and Tatum’s experiment with Neurospora crassa and the results. Neurospora crassa, which is a type of bread mold of the phylum Ascomycota, has provided a rich source of knowledge on “biosynthetic pathways.” Neurospora crassa was perfect substance for biosynthetic pathway experiment. Because it was cheap, easy to grow, and more importantly it is haploid for most of its life. Since Neurospora crassa is haploid, there exists only one copy of each gene so that researchers don’t need to consider about dominant and recessive alleles.

    The purpose of this lab was to change pennies from copper to silver to gold, like alchemists have attempted to do in history. Through the data and observations gathered throughout this experiment, it can be concluded that the pennies were not changed into a different element. For example, the density of the penny from 2005; which was the penny that was experimented on to see whether or not it could turn into silver; was 4.62 g/cm3 before the experiment and 4.89 g/cm3 by the end of the experiment. If this copper penny really would have turned into silver, then the density of the penny would be 10.49 g/cm3; which is the density of silver; by the end of the experiment. The penny may have turned silver in color, but this was only because it was plated in the zinc that was added to the beaker of water in the experiment.

    In this lab there were five different stations. For the first station we had to determine an unknown mass and the percent difference. To find the unknown mass we set up the equation Fleft*dleft = Fright*dright. We then substituted in the values (26.05 N * 41cm = 34cm * x N) and solved for Fright to get (320.5g). To determine the percent difference we used the formula Abs[((Value 1 - Value 2) / average of 1 & 2) * 100], substituted the values (Abs[((320.5 - 315.8) /

    When the steel is quenched, the heat energy within the center of the part is pulled out quickly. The process of cooling rapidly cooling down the steel creates lots of tinny grain boundaries on the surface. The small grain boundaries are called martensite, as seen in figure 1 picture C. Martensite is a very hard microstructure due to having a dense amount of grain boundaries. The martensite crystals
