Examples of sacrificial coating in the following topics:
- The process of coating a metal surface with another metal that is more likely to be oxidized is referred to as sacrificial coating.
- Cathodic protection replicates the effects of a sacrificial coating but with a more active metal.
- Using the same principle as sacrificial film coating, a sacrificial anode, made of a metal more active than the metal you want to protect, can be used to prevent corrosion on submerged or buried metal structures.
- The sacrificial anode will corrode before the metal it is protecting does.
- Galvanic sacrificial anode attached to the hull of a ship; here, the sacrificial anode shows corrosion but the metal it is attached to does not.
- This legendary vision is pictured on the coat
of arms of Mexico.
- Every level of Aztec society
was affected by the belief in the human responsibility to pay homage
to the gods, and anyone could serve as a sacrificial offering.
were responsible for collecting tributes and ensuring there were
enough goods for sacrificial ceremonies.
- These feats
of architectural display were the sites of large sacrificial
offerings and festivals, where Spanish reports said blood would run
down the steps of the pyramids.
- Weapons such as daggers and axes had a sacrificial meaning, symbolizing the heavenly power of the ruler.
- Examples of ritual bronze vessels include the numerous large sacrificial tripods known as dings and other distinct shapes such as gui and zun.
- Zun are wine and sacrificial vessels characterized by a tall cylindrical shape with no handles or legs and a mouth slightly broader than the body.
- The ritual books of China during the Zhou Dynasty describe who was allowed to use what kinds of sacrificial vessels.
- The leaves and fruits of many plants have waxy coatings, which may protect them from dehydration and small predators.
- The feathers of birds and the fur of some animals have similar coatings which serve as a water repellent.
- Monocot and dicot seeds develop in differing ways, but both contain seeds with a seed coat, cotyledons, endosperm, and a single embryo.
- The seed, along with the ovule, is protected by a seed coat that is formed from the integuments of the ovule sac.
- In dicots, the seed coat is further divided into an outer coat, known as the testa, and inner coat, known as the tegmen.
- When the seed coat forms from only one layer, it is also called the testa, though not all such testae are homologous from one species to the next.
- In monocot seeds, the testa and tegmen of the seed coat are fused.
- A glycocalyx(capsule or slime layer)is an external coating of bacteria with protective function, made mostly of polysaccharides.
- A glycocalyx, literally meaning "sugar coat", is a network of polysaccharides that project from cellular surfaces of bacteria, which classifies it as a universal surface component of a bacterial cell, found just outside the bacterium cell wall.
- This coat is extremely hydrated and stains with ruthenium red.
- To keep unit production costs under control, 3M studied the setups on its coating machines.
- Since the cost of chemical waste disposal was a major part of the cost of changing over a coating machine to make another product, 3M shortened the length of hoses that needed purging and redesigned the shape of the adhesive solution holding pan on the coating machine to be shallower. 3M also used quick-connect devices, disposable filters, and work teams to speed up setups.
- The result was that 3M could maintain low unit costs on its coating machines while producing small lots of hundreds of products to meet market demand quickly.
- They supply the muscular coat, ramify in the submucous coat, and are finally distributed to the mucous membrane.
- Nerve plexuses are found in the submucous coat and between the layers of the muscular coat as in the intestine.
- These murals also provide a window into the Terminal Preclassic sacrificial and inauguration rituals, such as bloodletting, that were practiced around 100 BCE.
- This colorful mural depicts a king practicing bloodletting, probably for an inauguration or other sacrificial purpose.
- The light-sensitive material was a thin coating of bitumen, which was dissolved in white petroleum, applied to the surface of the plate and allowed to set before use.
- Niépce had previously experimented with paper coated with silver chloride.
- Unlike earlier experimenters with silver salts, he succeeded in photographing the images formed in a small camera, producing his first results in 1816; however like his predecessors he was unable to prevent the coating from darkening all over when exposed to light for viewing.
- More interested in silver-based processes than Niépce had been, Daguerre experimented with photographing camera images directly onto a silver-surfaced plate that had been fumed with iodine vapor, which reacted with the silver to form a coating of silver iodide.
- Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image.
