The hardness ratio of the two sliding materials also has an effect on fretting wear. [14] However, softer materials such as polymers can show the opposite effect when they capture hard debris which becomes embedded in their bearing surfaces. They then act as a very effective abrasive agent, wearing down the harder metal with which they are in ...
Oxide jacking has caused concrete spalling on walls of the Herbst Pavilion at Fort Mason Center in San Francisco. The expansive force of rusting, which may be called oxide jacking or rust burst, is a phenomenon that can cause damage to structures made of stone, masonry, concrete or ceramics, and reinforced with metal components.
High-pressure water atomization is a processing method of bismuth brass. This is a way of rapidly solidifying the metal alloy. A liquid metal is dispersed into droplets by the impingement of high-pressure jets of water. It is a low-cost process to achieve a distribution of fine particles in iron, stainless steel, and low-alloy metal powders ...
DZR brass: Arsenic: Dezincification resistant brass with a small percentage of arsenic. Delta metal: 55: 41–43: 1–3% iron with the balance consisting of various other metals. The proportions used make the material harder and suitable for valves and bearings. Free machining brass (C360) 61.5: 35.5: 2.5–3.7: 0.35% iron: Also called 360 or ...
Galvanized nails and sheet metal ducts are also common. Architectural grade zinc is 90 to 95% recycled. Replacement costs are negligible with a long lifetime of 80 to 100 years for zinc roofing and 200 to 300 years for wall systems. [8] This long-life durability is a key component in durability.
masonry screw Confast screw multi-material screw blue screw self-tapping masonry screw Titen: A stainless or carbon steel screw for fastening wood, metal, or other materials to concrete or masonry. Concrete screws are commonly blue in color, with or without corrosion coating. They may either have a Phillips flat head or a slotted hex washer head.
Stainless steel, also known as "inox steel" does not stain, corrode, or rust as easily as ordinary steel. Pierre Berthier, a Frenchman, was the first to notice the rust-resistant properties of mixing chromium with alloys in 1821, which led to new metal treating and metallurgy processes, and eventually the creation of usable stainless steel.
Where a fastener forms its own thread in the component being fastened, it is called a screw. [3] This is most obviously so when the thread is tapered (i.e. traditional wood screws), precluding the use of a nut, [3] or when a sheet metal screw or other thread-forming screw is used. A screw must always be turned to assemble the joint.
