Abstract

Discontinuously reinforced aluminum (DRA) composites have many advantages over the unreinforced aluminum alloys and have found increasing applications in the automotive industry. The wear behavior plays a very important role in DRA composites for such applications. The commonly used apparatus for studying the DRA abrasive wear include pin-on-disk, block-on-ring, and pin-on-drum. The pins or blocks are the composites and the abrasive papers are bonded onto the counter parts. The main drawback of the block-on-ring and pin-on-drum techniques is that the contact area does not remain a constant during the initial testing period. In the pin-on-disk method, the abrasive testing conditions are not easily kept identical either. The abrasive particles are prone to be blunted and smeared by composites when running a single-track test and the sliding speed is not constant when running a spiral-track test. In this study, a modified pin-on-disk apparatus was developed. During the entire testing period, the contact area remains unchanged, and the composite pin can be always abraded y fresh abrasive particles. An aluminum alloy, AA 7075 was reinforced with 20 vol% SiC{sub p} at various particle sizes (82, 59, 37, 16, and 12 {micro}m).

Investigation of two-body abrasive wear

Conference Hirano, H; Levy, A

An investigation of two-body abrasive wear utilizing a pin specimen on a rotating SiC particle abrasive paper test device is described. The test materials were 7075 aluminum and 4340 steel which were thermally treated to attain a range of hardness, fracture toughness and yield strength values. Wear resistance is seen to correlate directly with hardness and yield strength for both materials. For the 4340 steel the wear resistance is inversely proportional to the fracture toughness; for the 7075 aluminum, the inverse proportionality is dependent upon the microstructure. The effect of an increase in hardness by heat treatment of an alloymore »« less

Abrasive wear behavior of MoSi{sub 2}/SiC and MoSi{sub 2}/ZrO{sub 2} composites

Journal Article Alman, D; Hawk, J; Petrovic, J - Scripta Metallurgica et Materialia

The volume wear behavior of MoSi{sub 2}/SiC and MoSi{sub 2}/ZrO{sub 2} composites was evaluated using 150 grit SiC particles in a pin-on-drum abrasion test. The addition of SiC whiskers or particles reduced the volume wear of the composite relative to monolithic MoSi{sub 2} by about a factor of two, with the SiC whisker containing composite having a slightly lower volume wear rate than the SiC particulate reinforced composite. The addition of partially-stabilized (PS)-ZrO{sub 2} particles lowered the volume wear of the composite relative to MoSi{sub 2}. The addition of unstabilized (US)-ZrO{sub 2} or fully-stabilized (FS)-ZrO{sub 2} particles to the MoSi{submore »« less

Friction and abrasion resistance of cast aluminum alloy-fly ash composites

Journal Article Rohatgi, P; Guo, R; Huang, P; ... - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

The abrasive wear properties of stir-cast A356 aluminum alloy-5 vol pct fly ash composite were tested against hard SiC{sub p} abrasive paper and compared to those of the A356 base alloy. The results indicate that the abrasive wear resistance of aluminum-fly ash composite is similar to that of aluminum-alumina fiber composite and is superior to that of the matrix alloy for low loads up to 8 N (transition load) on a pin. At loads greater than 8 N, the wear resistance of aluminum-fly ash composite is reduced by debonding and fracture of fly ash particles. Microscopic examination of the wornmore »« less

Abrasion and erosion testing of materials used in power production from coal

Conference Tylczak, Joseph; Adler, Thomas; Rawers, James

The Albany Research Center (ARC) has a long history of studying abrasive wear, related to mineral testing, handling, and processing. The center has also been instrumental in the design and development of wear test procedures and equipment. Research capabilities at ARC include Pin-on-Drum, Pin-on-Disk, and Dry Sand/Rubber Wheel abrasion tests, Jaw Crusher gouging test, Ball-on-Ball Impact test, and Jet erosion tests. Abrasive and erosive wear studies have been used to develop both new alloys and improved heat treatments of commercial alloys. As part of ARC’s newest iteration on wear testing to evaluate materials for use in new and existing pulverizedmore »« less

The abrasive wear of sintered titanium matrix-ceramic particle reinforced composites

Conference Alman, David; Hawk, Jeffrey - Wear

Particulate (TiC, TiB2 or Si3N4) reinforced Ti composites were produced by vacuum sintering (at 1400°C for 2 h). Ti+TiC composites could be sintered to high fractional densities (>93%), even at high TiC loadings (e.g., 40 volume percent (vol%)). No reactions were observed to occur between the Ti and TiC. By contrast, the Ti and TiB2 and Ti and Si3N4 reacted to form composites consisting of Ti, TiB and TiB2 and α-Ti(N), Ti5Si3, Ti3Si, and Ti2N, respectively. As a consequence, Ti was consumed and/or the reaction products intrinsically generated porosity during sintering. These composites were more difficult to consolidate via solidmore »« less
