The counterweights can move freely over threaded shafts. Design and construction of a machine for micro-abrasion-corrosion testing in simulated biological environments. The main drawback of corrosion is the release of metal ions into surrounding tissues which causes DNA damage, alterations associated with the etiology of cancer thus increasing the risk of local tumors, and the mechanical failure of the implant [7, 11].

Third, we use an NI USB data acquisition card to count encoder pulses and communicate between the user interface and the machine. Wilkinson, “Topographical Control of Cell Behavior: Finally, we use a 12V DC power source to power the system.

Schmidt, Engineering design, McGraw-Hill, Materials and methods The solution lies in the characterization of the wear and corrosion resistance properties of joint implant biomaterials. A low modulus to minimize bone reabsorption. As for the study of corrosion, we use electrochemical techniques such as Tafel polarization curves and electrochemical impedance spectroscopy EIS. Furthermore, combinations of materials with varying properties have been used in order to diminish the harmful effects generated by prosthetic parts.

Amazon Renewed Refurbished products with a warranty. For this design, three design concepts were created Table 2. Shopbop Designer Fashion Brands. The motivation of this study arises from the need to extend the service life of various devices used in orthopedic surgery, especially hip, knee, and shoulder joint replacements, among others. For every complete revolution of the motor shaft 16 pulses are released – translated to the rotations of the shaft of the reduction gearbox there are pulses per rotation.

Controller gain can also be modified by the user for the correct functioning materialles the unit Figure At this state of design we also identified technical difficulties, which lie in the adaptation of the actuators, the sensor system, and minimizing vo, number of parts, parameters that have a strong relationship with the modularity of the cirncia. From the materjales of view of engineering, a synovial joint presents behavior similar to a plain bearing, consisting as it does materoales layers of articular material cartilage arranged over bone tissue and forming a relatively hard bone structure in which the synovial fluid acts as a lubricant Figure 1 [8].


We can thus study the wear mechanisms and corrosion phenomena of biocompatible materials in contact with a balanced salt solution, representing the characteristics of body fluids. According to the matrix, the comparison between the three design proposals suggests Matefiales 3 as the best design, with a rating of 8. As an example, a variety of hard coatings originally used on cutting tools are being used as biomaterials since they are bio-inert, bio-compatible, and have properties highly resistant to wear and loe.

Meanwhile, its power will be controlled by an Arduino system with an Ardumoto Shield that can handle up to two motors with PWM. Such systems lead to various types materialez failure due primarily to frictional wear and corrosive phenomena, as shown in the diagram in Figure 2.

For all, rotational energy is to be provided by an electric motor with encoder controlled by Labview software interface. Joint replacements, due to the interactions between the various parts in contact calllster to constant movement, generate wear mechanisms from the action of friction between the surfaces and the contaminant particles between them, causing anything from thin cracks to deep grooves [10].

Because we are studying corrosive phenomena, the parts in contact with the balls were designed to be manufactured in EMPACK or Nylon 66, thus isolating the system. Amazon Advertising Find, attract, and engage customers. Acceptable resistance to cyclic loading generated by the joints.

In order to select the design with the best performance, an evaluation method was used that cross-compares the design concepts – in this case a combination of an objective tree and a weighted decision matrix. In the beginning of the functional analysis, the inputs and outputs of the system as a whole were identified in order to build a black box diagram that describes the main function.

Amazon Restaurants Food delivery from local restaurants. It also allows one to work in different work environments to perform the assembly of the parts, engineering blueprints, and cinematic simulations of the different elements Figure Learn more about Amazon Prime.


FIGURE ingenueria Among the electronics used in the development of machine we first have a Hall effect encoder, which generates a leading edge and a trailing edge signal for measuring motor spin.


After weighting the objective tree, the weighted decision matrix was created. To generate the simulated conditions, we designed an acrylic tank within which the test is conducted. The software used was Labviewwhich employs a programming language which is principally graphical in blocks. Among the electronics used in the development of machine we first have a Hall effect encoder, calpister generates a leading edge and a trailing edge signal for measuring motor spin.

Be the first to review this item Amazon Best Sellers Rank: The abrasive slurry will be mixed by a magnetic stirrer and transmitted by a peristaltic pump. Product details Paperback Publisher: To satisfy this need, all factors that influence joint replacement deterioration must be studied.

In light of the above, and considering the solid particles that accumulate in the body due to wear, there has been increasing interest in testing micro-abrasion, since this allows one to evaluate the frictional forces present between different contact surfaces as well as the effect of micro-particles, since abrasive particles in suspension enter the system [11, 22].

The technical specifications of the equipment are shown in Table 5: To do this, the objective tree was first constructed Figure 10 taking modularity and cost as our selection criteria, then grouping underneath these concepts the other selection criteria, stipulating their respective weightings according to the level of importance. Results and discussion 3.

Contact and frictional forces between the ball and the sample generate wear tracks. In order to adjust the contact force between the sample ciehcia the ball, a lever arm with counterweights was designed.

This study therefore describes a method to design and manufacture equipment that performs simultaneous micro-abrasion and electrochemical tests on various materials in simulated biological fluids for the purpose of observing their behavior and viability as a biomaterial.
