Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1] Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). [2]
This also inversely affects the depth of the case; i.e., a high carbon steel will form a hard, but shallow case. [14] A similar process is the trademarked "Nu-Tride" process, also known incorrectly as the "Kolene" process (which is the company's name), includes a preheat and an intermediate quench cycle.
Case-hardening or carburization is the process of introducing carbon to the surface of a low-carbon iron, or more commonly a low-carbon steel object, in order to harden the surface. Iron which has a carbon content greater than ~0.02% is known as steel .
The Philippines' Bureau of Agriculture and Fisheries Product Standards (Filipino: Kawanihan ng mga Pamantayan sa Produktong Pansaka at Pampangisdaan, abbreviated as BAFS), is an agency of the Philippine government under the Department of Agriculture responsible for setting and implementing standards for fresh primary and secondary processed agricultural and fishery products.
The cryogenic treatment process was invented by Ed Busch (CryoTech) in Detroit, Michigan in 1966, inspired by NASA research, which later merged with 300 Below, Inc. in 2000 to become the world's largest and oldest commercial cryogenic processing company after Peter Paulin of Decatur, IL collaborated with process control engineers to invent the world's first computer-controlled "dry" cryogenic ...
ABS-CBN Film Restoration Project, also known as Sagip Pelikula, is a digital film restoration project of ABS-CBN Corporation in partnership with Central Digital Lab. The project is headed by Leo Katigbak of ABS-CBN Film Archives and Manet Dayrit of Central Digital Lab.
In some old processes, the film emulsion was hardened during the process, typically before the bleach. Such a hardening bath often used aldehydes, such as formaldehyde and glutaraldehyde. In modern processing, these hardening steps are unnecessary because the film emulsion is sufficiently hardened to withstand the processing chemicals.
The year 2008 also marks Cuneta's 30th anniversary in the industry, and the film serves as offering to fans. [2] The film was also released in international cinemas. Caregiver had its premiere in Alex Theatre in Glendale, California on May 31, 2008. Many Filipino caregivers working far from California travelled in to watch the film. [3]
